The methods provided herein isolate one or more target(s) of interest from flowing matter using fluidic devices that detect, capture, adsorb, and/or remove the target(s) of interest (alternatively called “disease-causing material(s)” or “material(s) of interest”) from biological fluids and produce an eluant for the subsequent diagnosis and treatment of disease based thereon. Devices are provided herein that are effective in and configured to isolate target(s) of interest from flowing matter by detecting, capturing, adsorbing, and/or removing target(s) of interest from biological fluids. The devices may further be configured to evaluate and/or identify the target(s) of interest and/or diagnose a disease based on the target(s) of interest isolated from the biological fluid. The devices may further be configured to provide information about the target(s) of interest to a system for evaluation and/or identification of the target(s) of interest. The target(s) of interest isolated by the device may be sufficiently preserved by the devices and methods herein that the disease-causing material may be transferred to and evaluated by a second system or device by traditional methods known to one of skill in the art.
The detection, capture, adsorption, and/or removal of the disease-causing material from the biological fluids itself may result in a treatment for the disease in a subject and/or reduction or elimination of symptoms of the disease in the subject. The detection, capture, adsorption, and/or removal of the disease-causing material from the biological fluids may provide practitioners with sufficient information to treat a disease or symptoms thereof in a subject, without need for further identification of the disease-causing material. The detection, capture, adsorption, and/or removal of the disease-causing material from the biological fluids may be followed by evaluation of the disease-causing material isolated by and eluted by the device. The evaluation and/or analysis of the eluted materials of interest (or portions thereof or altered versions thereof) may be conducted by the device or by other systems or devices which receive the eluted materials of interest, or a portion thereof, or an altered form thereof, or receive information about the eluted materials of interest. Identification of the disease-causing material or the disease by the device or by another device receiving the disease-causing material, a portion thereof, an altered form of the disease-causing material, or information about the disease-causing material, may be used to reduce or eliminate symptoms of the disease in the subject. In some embodiments, knowledge of a substance coated on the wall of a channel of a device combined with a determination that the substance captured, isolated, adsorbed or otherwise detected from the biological fluid passed through the channel is sufficient to diagnose a disease and/or determine a treatment for the subject, without further evaluation of the material isolated by the device.
The method presented herein is intended to be used for the isolation of targets of interest from flowing matter, and in the diagnosis and treatment of disease. The method presented herein provides a method of capturing and collecting targeted analytes from fluids by flowing said fluids through a multi-directional channel that is coated with a polypeptide antibiotic and/or other materials. However, those familiar with the art would appreciate the broad applicability of this method.
Provided herein is a method for the capture and isolation of materials of interest comprising: flowing a sample through a fluidic cartridge comprising a multi-directional fluidic channel between an inlet and an outlet; adsorbing one or more materials of interest on at least one wall of the multi-directional fluidic channel; washing the multidirectional fluidic cartridge channel with a wash buffer (eluant) to separate the adsorbed materials of interest from a residual sample matter that is not of interest; discarding said wash buffer containing the residual sample matter that is not of interest; flowing an eluant through the fluidic cartridge containing the adsorbed materials of interest on the at least one wall in the multi-directional fluidic channel between the inlet and the outlet, collecting and concentrating the materials of interest in an eluate; and collecting an amount of the eluate containing the one or more concentrated materials of interest eluted from the sample. In some embodiments, the sample comprises an additive before flowing through the fluidic cartridge. In some embodiments the additive comprises one or more of: an EDTA; a K2EDTA; a heparin compound; a fluoride; an oxalate; a sodium citrate; a sodium polyanethol sulfonate (SPS); an Acid Citrate Dextrose Solution; a distilled H2O; or a saline.
In some embodiments, a substance is coated on the at least one wall of the multi-directional fluidic channel.
In some embodiments, the eluant is an elution buffer. In some embodiments, the eluant is a lysis buffer.
In some embodiments, the eluate containing the concentrated materials of interest is purified by introducing the eluate into a spin column. In some embodiments, the spin column is placed in a centrifuge for centrifugation. During centrifugation, target sample materials are entrapped in the spin column matrix, while other unwanted materials pass through the spin column matrix into the collection vial. The collection vial is discarded. The targeted, isolated sample material entrapped in the spin column matrix is then released from the matrix and collected into a clean collection vial by washing the matrix with ethyl alcohol.
In some embodiments, the collected isolated materials of interest are analyzed. In some embodiments, the collected isolated materials of interest (or portions thereof or altered versions thereof) are analyzed by other systems or devices which receive the eluted materials of interest, or a portion thereof, or an altered form thereof, or receive information about the eluted materials of interest. In some embodiments, identification of the disease-causing material or the disease by the device or by another device receiving the disease-causing material, a portion thereof, an altered form of the disease-causing material, or information about the disease-causing material, is used to reduce or eliminate symptoms of the disease in the subject.

In some embodiments of the method, the eluant of interest retained from the fluidic cartridge outlet is washed using spin filtration.
In some embodiments of the method, the elution buffer lyses and breaks open the pathogens, thereby killing them, leaving them suspended in the eluate. In some embodiments of the method, the elution buffer breaks the bonds between the pathogens and colistin/vancomycin, thereby leaving the pathogens alive and intact in the eluate and available for culturing.
In some embodiments of the method, detection of the presence or amount of materials of interest captured within the multidirectional, polypeptide antibiotic coated channel is performed by analyzing the materials of interest following elution from the fluidic cartridge using said elution/lysis buffer. In some embodiments, an analysis method is selected from the group comprising: cell counting, MALDI-TOF MS (matrix assisted laser desorption ionization-time of flight mass spectrometry), mass spectrometry, PCR (polymerase chain reaction), biosensing, flow cytometry, and fluorescent labeling. In some embodiments, the eluted material of interest is analyzed using at least one of: a polymerase chain reaction (PCR), a matrix-assisted laser desorption/ionization-time of flight, (MALDI-TOF), a nuclear magnetic resonance (NMR) spectroscopy, culturing, a fluorescence in situ hybridization (FISH), optically active microbeads and optically active nanoparticles.
Provided herein is a method of isolating one or more target(s) of interest from a sample of flowing matter using fluidic devices that detect, capture, adsorb, and/or remove the target(s) of interest (alternatively called “disease-causing material(s)” or “material(s) of interest”) from biological fluids and the subsequent diagnosis and treatment of disease based thereon. The method comprises; (1) flowing the sample through a multidirectional fluidic cartridge channel that is coated with a substance, causing the sample to come in contact with the coating substance, thereby forming a bond between said substance and said the materials of interest within the sample; (2) separating the bound materials of interest from sample matter that is not of interest by washing the multidirectional fluidic cartridge channel with a wash buffer and then discarding said wash buffer containing the residual sample matter that is not of interest; (3) collecting the materials of interest by flowing an elution buffer (eluant) through the multidirectional fluidic cartridge channel, thus concentrating the materials of interest in an eluate; and (4) the eluate containing the concentrated materials of interest is purified by introducing the eluate into a spin column. The spin column is placed in a centrifuge for centrifugation. During centrifugation, target sample materials are entrapped in the spin column matrix, while other unwanted materials pass through the spin column matrix into the collection vial. The collection vial is discarded. The targeted, isolated sample material entrapped in the spin column matrix is then released from the matrix and collected into a clean collection vial by washing the matrix with ethyl alcohol. In some embodiments, the collected isolated materials of interest are analyzed. Analysis of the isolated materials of interest comprises a polymerase chain reaction (PCR)-based assay, a nuclear magnetic resonance (NMR) spectroscopy, a matrix-assisted laser desorption/ionization-time of flight (MALDI-TOF), a fluorescence in situ hybridization (FISH), an immunoassay, an enzyme-linked immunosorbent assay (ELISA), optically active microbeads, optically active nanoparticles, a culturing assay with optional staining, or a combination thereof.

Provided herein is a method for the capture and isolation of materials of interest comprising: flowing a sample through a fluidic cartridge comprising a multi-directional fluidic channel between an inlet and an outlet; adsorbing one or more materials of interest on at least one wall of the multi-directional fluidic channel; washing the multidirectional fluidic cartridge channel with a wash buffer (eluant) to separate the adsorbed materials of interest from a residual sample matter that is not of interest; discarding said wash buffer containing the residual sample matter that is not of interest; flowing an eluant through the fluidic cartridge containing the adsorbed materials of interest on the at least one wall in the multi-directional fluidic channel between the inlet and the outlet, collecting and concentrating the materials of interest in an eluate; and collecting an amount of the eluate containing the one or more concentrated materials of interest eluted from the sample.
Provided herein is a kit for the capture and adsorption of materials of interest comprising: a fluidic cartridge with an inlet and an outlet; a multidirectional fluidic channel between the inlet and the outlet; said multidirectional fluidic channel comprising at least one wall; a substance coating an inside wall of the multidirectional fluidic channel; and an eluant for eluting the at least one material of interest from the multidirectional fluidic channel. In some embodiments, the eluant is an elution buffer. In some embodiments, the eluant is a lysis buffer.
The presence of bacteria in the circulatory blood initiates a cascade of local and systemic regulatory mechanisms that often result in sepsis. Sepsis afflicts over 1.5 million Americans annually and has an associated mortality rate ranging from 25-50%. Sepsis is the leading cause of death of the critically ill in the United States, costing the U.S. over $24 Billion in treatment annually. With mortality rates as high as 50% for certain bloodstream infections and fewer antibiotics in development, there exists a tremendous clinical need to address this growing global health problem of sepsis.
A diagnosis of a septic episode is made from blood cultures. Blood cultures consist of a blood culture bottle inoculated with blood from the patient and incubated. It typically takes between 8-36 hours for a blood culture vial to be flagged as positive. The positive flag is followed by identification testing and typically requires two or more additional days. Treatment of patients using the correct antibiotic regime improves patient outcomes, decreases mortality rates, decreases length of hospital stay, and lowers hospital costs. The method herein describes a fluidic cartridge capable of expediting organism detection and identification directly from blood through reduction and/or elimination of the need for bacterial culturing.
Polymyxin, also known as colistin, is a cationic polypeptide antibiotic used for the treatment of Gram-negative infection and for detoxifying endotoxin. The positive charge of polymyxin, or colistin, allows for binding to the negatively charged outer membrane of Gram-negative pathogens and endotoxin. Although it is a powerful antibiotic, its use is limited due to its nephro- and neuro-toxicity. Therefore, its intravenous use is limited. Vancomycin is a polypeptide antibiotic that is commonly used for the treatment of Gram-positive infections. Vancomycin interacts with the cell wall of Gram-positive pathogens and inhibits bacterial cell wall assembly. This leads to activation of bacterial autolysins that destroy the cell wall by lysis. However, vancomycin is nephrotoxic when administered systemically. It is known that polymyxin, immobilized on beads, is capable of absorbing endotoxin. However, the use of beads, nanoparticles, porous materials, and fibers have proven inefficient in the capture of endotoxin from fluids such as blood. Also, none of these technologies are capable of efficient capture and adsorption of blood-borne Gram-positive and Gram-negative pathogens, both of which are root causes of sepsis.
As used herein, and unless otherwise specified, the phrase “material of interest”, “target(s) of interest,” “target material of interest”, “disease-causing material(s),” “materials of interest,” or “disease material,” used synonymously herein, means one or more disease materials comprising cancer cells, circulating tumor cells, peptides, beta amyloid, proteins, enzymes, toxins, diseased cells, infectious microorganisms, cells, parasites, fungi, viruses, microorganisms, bacteria, bacterial toxin, quorum sensing proteins or receptors, lipopolysaccharide, cytokines, IL-Iβ, IL-4, IL-6, IL-8, IL-10, IL-11, IL-13, IL-15, IL-16, tumor necrosis factors, procalcitonin, pathogen-associated molecular patterns, C reactive protein, or a small or protein bound biological molecule relevant to liver failure.
As used herein, and unless otherwise specified, the term “eluant” or “eluent” means a fluid used to elute a substance. Alternatively, an “eluant” or “eluent” is a substance used as a solvent in separating materials in elution. The eluant or eluent is the “carrier” portion of the mobile phase. For example, it moves the analytes through the chromatograph. In liquid chromatography, the eluent is the liquid solvent; in gas chromatography, it is the carrier gas. As used herein, and unless otherwise specified, the term “elute”, “eluting”, “elution”, and like terms, means to wash out or extract, or the process of washing out or extracting; or more specifically to remove (an adsorbed substance) by washing with a solvent. In analytical and organic chemistry, elution is the process of extracting one material from another by washing with a solvent; as in washing of loaded ion-exchange resins to remove captured ions. Further, as used herein, and unless otherwise specified, the term “eluate” means a solution obtained by elution. Still further, as used herein the term “eluate” means the solute, “eluted material of interest”, alternatively called the “eluted target(s) of interest,” “eluted disease-causing material(s),” “eluted materials of interest,” or “eluted disease material,” obtained from the elution process.
It specifically includes both the analytes and solutes passing through the column, while the eluent is only the carrier.
As used herein, and unless otherwise specified, the term “lysis”, “lysing” and similar terms, means the disintegration of a cell by rupture of the cell wall or membrane.
As used herein, and unless otherwise specified, the term “buffer”, “buffering”, pH buffer, hydrogen ion buffer, and similar terms, refers to a solution, or an aqueous solution consisting of a mixture of a weak acid and its conjugate base, or vice versa, that can resist pH change upon the addition of an acidic or basic component. It is able to neutralize small amounts of added acid or base, thus maintaining the pH of the solution relatively stable.
As used herein, and unless otherwise specified, the term “biosensing”, “biosensor” and similar terms, refer to the use of nanoscale or microscale biological sensors. A biosensor is an analytical device, used for the detection of an analyte that combines a biological component with a physicochemical detector. The sensitive biological element, (e.g. tissue, microorganisms, organelles, cell receptors, enzymes, antibodies, nucleic acids, etc.), is a biologically derived material or biomimetic component that interacts, binds, or recognizes with the analyte under study. The biologically sensitive elements can also be created by biological engineering. In a biosensor, the bioreceptor is designed to interact with the specific analyte of interest to produce an effect measurable by the transducer. High selectivity for the analyte among a matrix of other chemical or biological components is a key requirement of the bioreceptor. While the type of biomolecule used can vary widely, biosensors can be classified according to common types of bioreceptor interactions involving: antibody/antigen, enzymes/ligands, nucleic acids/DNA, cellular structures/cells, or biomimetic materials. The bioreceptor is a biomolecule that recognizes the target analyte whereas the transducer converts the recognition event into a measurable signal. The uniqueness of a biosensor is that the two components are integrated into one single sensor.
In some embodiments, the device is configurable be used as a biosensor by adding a fluorescent label to the bacteria, colistin/vancomycin or other endotoxin adsorbing agent, with the fluorescence being activated or increased with target binding to the channel wall. As used herein, the colistin and vancomycin are defined as “ligands”. As used herein, a ligand is a substance that forms a complex with a biomolecule to serve a biological purpose. In protein-ligand binding, the ligand is usually a molecule which produces a signal by binding to a site on a target protein. The fluorescence of the channel is then read directly using a fluorescence detector.
As used herein, and unless otherwise specified, the term “about” or “approximately” means an acceptable error for a particular value as determined by one of ordinary skill in the art, which depends in part on how the value is measured or determined.

As used herein, and unless otherwise specified, the terms “comprises”, “comprising”, or any other variation thereof, are intended to cover a nonexclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
As used herein, and unless otherwise specified, the terms “user”, “subject” or “patient” are used interchangeably. As used herein, the terms “subject” and “subjects” refers to an animal (e.g., birds, reptiles, and mammals), preferably a mammal including a primate (e.g., a monkey, chimpanzee, and a human) and a non-primate (e.g., a camel, donkey, zebra, cow, pig, horse, cat, dog, rat, and mouse). In certain embodiments, the mammal is 0 to 6 months old, 6 to 12 months old, 1 to 5 years old, 5 to 10 years old, 10 to 15 years old, 15 to 20 years old, 20 to 25 years old, 25 to 30 years old, 30 to 35 years old, 35 to 40 years old, 40 to 45 years old, 45 to 50 years old, 50 to 55 years old, 55 to 60 years old, 60 to 65 years old, 65 to 70 years old, 70 to 75 years old, 75 to 80 years old, 80 to 85 years old, 85 to 90 years old, 90 to 95 years old or 95 to 100.
As used herein, and unless otherwise specified, the term “transverse force”, (also called the Euler force) is the tangential force that is felt in reaction to any angular acceleration, also known as azimuthal acceleration or transverse acceleration. It is an acceleration that appears when a non-uniformly rotating reference frame is used for analysis of motion and there is variation in the angular velocity of the reference frame's axes. This definition is typically restricted to a reference frame that rotates about a fixed axis. The Euler force (F) is related to the Euler acceleration by “F=ma”, where “a” is the Euler acceleration and m is the mass of the body. Said another way, the Euler force will be felt by a person riding a merry-go-round. As the ride starts, the Euler force will be the apparent force pushing the person to the back of the horse, and as the ride comes to a stop, it will be the apparent force pushing the person towards the front of the horse. A person on a horse close to the perimeter of the merry-go-round will perceive a greater apparent force than a person on a horse closer to the axis of rotation.

The methods provided herein isolate one or more target(s) of interest from flowing matter using fluidic devices that detect, capture, adsorb, and/or remove the target(s) of interest (alternatively called “disease-causing material(s)” or “material(s) of interest”) from biological fluids and the subsequent diagnosis and treatment of disease based thereon. Devices are provided herein that are effective in and configured to isolate target(s) of interest from flowing matter by detecting, capturing, adsorbing, and/or removing target(s) of interest from biological fluids. The devices may further be configured to evaluate and/or identify the target(s) of interest and/or diagnose a disease based on the target(s) of interest isolated from the biological fluid. The devices may further be configured to provide information about the target(s) of interest to a system for evaluation and/or identification of the target(s) of interest. The target(s) of interest isolated by the device may be sufficiently preserved by the devices and methods herein that the disease-causing material may be transferred to and evaluated by a second system or device by traditional methods known to one of skill in the art.
The detection, capture, adsorption, and/or removal of the disease-causing material from the biological fluids itself may treat the disease in a subject and/or reduce or eliminate symptoms of the disease in the subject when the biological fluid (now having a reduced amount of disease-causing material therein, or now having the disease-causing material removed therefrom) is returned to the subject. As described herein, the device comprising the multidirectional channel is configurable for use to continuously filter a patient's blood in order to remove pathogens/endotoxins, thereby reducing the pathogen load and limiting the sepsis response. In some embodiments, the detection, capture, adsorption, and/or removal of the disease-causing material from the biological fluids provide practitioners with sufficient information to treat a disease in a subject or symptoms thereof, without need for further identification of the disease-causing material. In some embodiments, the detection, capture, adsorption, and/or removal of the disease-causing material from the biological fluids is followed by evaluation of the disease-causing material isolated by and eluted by the device. In some embodiments, the evaluation and/or analysis of the eluted materials of interest (or portions thereof or altered versions thereof) are conducted by the device or by other systems or devices which receive the eluted materials of interest, or a portion thereof, or an altered form thereof, or receive information about the eluted materials of interest. In some embodiments, the identification of the disease-causing material or the disease by the device or by another device receiving the disease-causing material, a portion thereof, an altered form of the disease-causing material, or information about the disease-causing material, is used to reduce or eliminate symptoms of the disease in the subject. In some embodiments, knowledge of a substance coated on the inner wall of a channel of a device combined with a determination that the substance captured, isolated, adsorbed or otherwise detected a material from the biological fluid passed through the channel is sufficient to diagnose a disease, determine a treatment for the subject, without further evaluation of the material isolated by the substance.
The presently described embodiments relate to a membrane-free pathogen adsorption fluidic cartridge technology that is capable of continuous flow. The working principle relies on three components: 1) polypeptide antibiotics bonded to the fluidic cartridge channel walls, 2) fluidic flow in curved or multidirectional channel structures, such as a spiral or helix, eliminating the need for membrane-based filters or external forces, and 3) the elution/lysis buffer (eluent or eluant) that allows for the elution of the materials of interest bound to the channel wall(s).
The described embodiments use a curved channel of a spiral or helical fluidic cartridge to introduce centrifugal force upon particulates (i.e. bacteria and endotoxin) flowing in a fluid (i.e. blood, saline, urine) to facilitate improved separation, capture, and removal of such particulates from the fluid. As these particulates flow through the channel, the particulates are forced toward the channel sidewalls, in a position offset from the center of the channel. The combination of centrifugal and fluidic forces in a helical- or spiral-shaped multidirectional channel allows for concentration of particulates near the polypeptide antibiotic functionalized sidewalls for capture and adsorption of bacteria and endotoxin.
In one example, as illustrated in the non-limiting
The polypeptide antibiotics described herein, including polymyxin (for Gram-negative bacteria) and vancomycin (for Gram-positive bacteria), are antibiotic substances having a strong affinity for the outer membrane of various strains of Gram-positive and Gram-negative bacteria, as well as an affinity for endotoxins. This allows for capture and adsorption of these biologics.
In another example, also as illustrated in the non-limiting
In some embodiments, the eluant is an elution buffer. In some embodiments, the eluant is a lysis buffer. In some embodiments, the eluate containing the concentrated materials of interest is purified by introducing the eluate into a spin column. In some embodiments, the spin column is placed in a centrifuge for centrifugation. During centrifugation, target sample materials are entrapped in the spin column matrix, while other unwanted materials pass through the spin column matrix into the collection vial. The collection vial is discarded. The targeted, isolated sample material entrapped in the spin column matrix is then released from the matrix and collected into a clean collection vial by washing the matrix with ethyl alcohol.
In some embodiments, the collected isolated materials of interest are analyzed. In some embodiments, the collected isolated materials of interest (or portions thereof or altered versions thereof) are analyzed by other systems or devices which receive the eluted materials of interest, or a portion thereof, or an altered form thereof, or receive information about the eluted materials of interest. In some embodiments, identification of the disease-causing material or the disease by the device or by another device receiving the disease-causing material, a portion thereof, an altered form of the disease-causing material, or information about the disease-causing material, is used to reduce or eliminate symptoms of the disease in the subject.
In some embodiments, the multi-directional fluidic channel is composed of at least one thermoplastic polymer base material that has at least one surface exposed functional group. In some embodiments, the thermoplastic polymer base material comprises: at least one exposed surface exposed wherein the thermoplastic polymer base material comprises at least one exposed surface selected from the functional group consisting of: a carbonyl group, a carboxyl group, an alcohol group, an amino group, a chloride group, a styrene group, an alpha-halogenated acyl group, a benzyl group, and an isocyanic acid groups, and a remaining thermoplastic polymer base material further comprises other polymers or copolymers comprising: a polyvinyl chloride, a polyvinyl acetate, a polyvinyl benzene, a polytetrafluoroethylene, a polyamide, an acrylamide, a polyurethane, a polyethylene, a polyethylene terephthalate, a polydimethylsiloxane, a polyacrylonitrile, a polycarbonate, an acetal, a polyethylene, a polypropylene, or a polymethyl methacrylate. In some embodiments, the thermoplastic polymer base material is polycarbonate.
Among the materials listed, polycarbonate derivatives are suitable for the carrier due to the exposed carbonyl groups and biocompatibility. The exposed carbonyl groups on the polycarbonate surface undergo nucleophilic addition by the amine groups of the polypeptide antibiotic, such as colistin or vancomycin. This reaction results in scission of the polymer chain and the formation of a terminal carbamate. Addition of the polypeptide antibiotic containing one or more amine groups results in a polycarbonate surface decorated with the polypeptide antibiotic, which is available for subsequent capture of bacteria and/or endotoxin (
In some embodiments, a substance is coated on the at least one wall of the multi-directional fluidic channel.
In some embodiments, the substance coating the channel wall comprises a fixed, covalently-bonded polypeptide antibiotic. In some embodiments, the fixed, covalently-bonded polypeptide antibiotic is polymyxin. In some embodiments, the amount of polymyxin fixed is about 0.5 mM to about 50 mM. In some embodiments, the amount of polymyxin fixed is at least about 0.5 mM. In some embodiments, the amount of polymyxin fixed is at most about 50 mM.

Provided herein is a method of isolating one or more target(s) of interest from a sample of flowing matter using fluidic devices that detect, capture, adsorb, and/or remove the target(s) of interest (alternatively called “disease-causing material(s)” or “material(s) of interest”) from biological fluids and the subsequent diagnosis and treatment of disease based thereon. The method comprises; (1) flowing the sample through a multidirectional fluidic cartridge channel that is coated with a substance, causing the sample to come in contact with the coating substance, thereby forming a bond between said substance and said the materials of interest within the sample; (2) separating the bound materials of interest from sample matter that is not of interest by washing the multidirectional fluidic cartridge channel with a wash buffer and then discarding said wash buffer containing the residual sample matter that is not of interest; (3) collecting the materials of interest by flowing an elution buffer (eluant) through the multidirectional fluidic cartridge channel, thus concentrating the materials of interest in an eluate; and (4) the eluate containing the concentrated materials of interest is purified by introducing the eluate into a spin column. The spin column is placed in a centrifuge for centrifugation. During centrifugation, target sample materials are entrapped in the spin column matrix, while other unwanted materials pass through the spin column matrix into the collection vial. The collection vial is discarded. The targeted, isolated sample material entrapped in the spin column matrix is then released from the matrix and collected into a clean collection vial by washing the matrix with ethyl alcohol. In some embodiments, the collected isolated materials of interest are analyzed. Analysis of the isolated materials of interest comprises a polymerase chain reaction (PCR)-based assay, a nuclear magnetic resonance (NMR) spectroscopy, a matrix-assisted laser desorption/ionization-time of flight (MALDI-TOF), a fluorescence in situ hybridization (FISH), an immunoassay, an enzyme-linked immunosorbent assay (ELISA), optically active microbeads, optically active nanoparticles, a culturing assay with optional staining, or a combination thereof.
In some embodiments, the sample is selected from the group consisting of a blood, a serum, a plasma, a urine, a cerebral spinal fluid, a bronchial fluid, another bodily fluid, a homogenized tissue, a homogenized food sample, and a combination thereof.
In some embodiments, the wash buffer comprises a saline, an ethanol, a sterile H2O, or a combination thereof.
