This application claims the benefit of Korean Patent Application Serial No. 10-2019-0092556, filed on Jul. 30, 2019 and Korean Patent Application Serial No. 10-2019-0149799, filed on Nov. 20, 2019 in the Korean Intellectual Property Office; the disclosure of which is incorporated herein in its entirety by reference.
The present disclosure relates to a multiple biomarker simultaneous analysis apparatus and method.
Viruses are pathogens smaller than 1 μm in size and cannot be observed even with an optical microscope, and an electron microscope is required to see viruses with the naked eye. In addition, a drug control method that directly acts on viruses has not yet been developed. In the past, electron microscopy and serological methods were mainly used for virus diagnosis. In a method using an electron microscope, the presence of a virus can be confirmed, but it is impossible to diagnose a species based on its morphological characteristics. Among serological methods, an enzyme-linked immunosorbent assay has about 1000 times lower detection sensitivity than the most commonly used diagnostic method or polymerase chain reaction (PCR) diagnostic method, and diagnosis often fails due to an unexpected non-specific reaction between an antibody and a test sample.
For this reason, precise and rapid diagnosis is a prerequisite for the management of viral diseases. Meanwhile, in a reverse transcription—polymerase chain reaction (RT-PCR) method, which is commonly used for precise diagnosis in plant viruses, the primer used determines the specificity and precision of diagnosis. In the case of commonly used primers, these primers are designed for the purpose of virus gene cloning and are not species-specific in many cases. Because there are cases where non-specific products are produced by plants or other viruses, they are often unsuitable for use in diagnosis. In addition, an RT-PCR method is performed using various types of primers so as to diagnose several types of viruses from the same sample such that a large amount of diagnostic cost and labor is required.
Meanwhile, because, in a diagnostic device according to the related art, a reaction is performed by adding a reaction reagent, a detection reagent, etc. to a sample, errors occur at a relatively high frequency in the detection result due to each of the added reagents. A process of performing a plurality of repeated experiments was required for accurate diagnosis. If it is possible to prevent the occurrence of errors due to the added reagent, the cost and time required for diagnosis may be reduced.
The present disclosure provides an analysis apparatus capable of detecting multiple biomarkers only by analyzing a single tip as binding materials capable of being specifically bound to different detection target materials are formed in a tip.
The present disclosure also provides an analysis apparatus in which, as binding materials capable of being specifically bound to a detection target are formed in a tip and an analysis process is performed while the tip is moved, the occurrence of analysis errors due to components other than a sample may be significantly reduced.

Hereinafter, a multiple biomarker simultaneous analysis apparatus 200 according to an embodiment of the present disclosure will be described in more detail with reference to the accompanying drawings.
First, a cartridge 100, which is mounted on the multiple biomarker simultaneous analysis apparatus 200 and analyzed by the multiple biomarker simultaneous analysis apparatus 200, will be described in detail with reference to
Referring to
A sample S of an analyte is injected into the sample well 101, and the sample S may be a blood sample of the analyte, but the sample S may be extracted from a person to be tested, such as sweat, saliva, runny nose, sputum, urine, feces, carriers, etc. As long as the sample S may contain a detection target material T capable of determining the presence of the detection target material Tin the sample S, embodiments of the present disclosure are not limited thereto.
A tip 110 is inserted into the tip well 102.
The front end of the tip 110 includes a surface on which binding materials specifically bound to the detection target material T are sol-gel-spotted. Specific details on the sol-gel spotting of the binding materials contain the contents of the present applicant's prior patent applications KR 10-2011-0039535 (Apr. 27, 2011), PCT-KR2011-003105 (Apr. 27, 2011), KR 10-2006-0008926 (Jan. 27, 2006), PCT-KR2007-000390 (Jan. 23, 2007), KR 10-2013-0047564 (Apr. 29, 2013), PCT-KR2013-003657 (Apr. 26, 2013), and KR 10-2018-0125995 (Oct. 22, 2018), and the contents of the above patent applications are included in the contents of this patent application as a whole.
The tip 110 is detachably inserted into the tip well 102, and a component capable of being bound to a detection target material (biomarker) included in the target sample S by an immunological or non-immunological method is coupled to the lower surface of the tip 110 using a sol-gel spot. At this time, the binding materials coupled to the lower surface of the tip 110 may be an antigen, an antibody, or an aptamer, but as long as the binding materials are materials capable of being specifically bound to the detection target material, embodiments of the present disclosure are not specifically limited thereto.
The binding materials coupled to the lower surface of the tip 110 are, for example, Anti-HIV 1/2 detecting antigen, Anti-HCV detecting antigen, HBsAg detecting antibody, Influenza A Antibody, Influenza B Antibody, RSV Antibody, SARS-CoV-2 Antibody, SARS-CoV-2 Antigen, CA19-9 antibody, AFP antibody, CEA antibody, PSA antibody, CA 125 antibody, CA 15-3 antibody, CA 242 antibody, CYFRA21-1 antibody, SCCA antibody, NSE antibody, HE4 antibody, Canine-based CDV, CPV, CPIV, CAV-2 and CCoV, Feline-based FCV, FPV, FVR (FHV), FIP (FCoV) and Chl. Felis, etc., but embodiments of the present disclosure are not limited thereto.
A single number or a plurality of bonding materials may be coupled to the lower surface of the tip 110. Also, a single type of bonding material or a plurality of types of bonding materials may be coupled to the lower surface of the tip 110. Specifically, the bonding materials coupled to the lower surface of the tip 110 are arranged in one column or one row for each type of the bonding materials, and the arrangement of all bonding materials is 2×2, 3×3, 4×4, 5×5, etc. However, embodiments of the present disclosure are not limited thereto. That is, as long as all binding materials are coupled to the lower surface of the tip 110 and may be bound to the detection target material included in the sample S through supporting of the sample S, the shape of the arrangement is not limited. In another embodiment of the present disclosure, in order to minimize the error of an analysis method through a triplet test, one binding material may be coupled to the lower surface of the tip 110 in an arrangement of 3 rows per one binding material.
In addition, in another embodiment of the present disclosure, the binding materials coupled to the lower surface of the tip 110 may include two or more selected from the group consisting of Influenza A Antibody, Influenza B Antibody, RSV Antibody, and SARS-CoV2 Antibody.
In addition, in another embodiment of the present disclosure, the binding materials coupled to the lower surface of the tip 110 may include two or more selected from the group consisting of CA19-9 antibody, AFP antibody, CEA antibody, PSA antibody, and CA 125 antibody (see
In addition, in another embodiment of the present disclosure, the binding materials coupled to the lower surface of the tip 110 may include two or more selected from the group consisting of CA 15-3 antibody, CA 242 antibody, CYFRA21-1 antibody, SCCA antibody, NSE antibody, and HE4 antibody.
The detection target material (biomarker) that is specifically bound to the binding material coupled to the lower surface of the tip 110 may be, for example, a nucleic acid, a peptide, a protein, a small molecule material, a virus, an influenza virus, or a cell. However, embodiments of the present disclosure are not limited thereto.
At the rear end of the tip 110, a tip coupling hole 110a for coupling with a tip coupling portion 220 to be described later may be formed at the rear end of the tip 110, and the tip coupling portion 220 is inserted into the tip coupling hole 110a, so that coupling between the tip coupling portion 220 and the tip 110 may be made.
A punching tip 120 is inserted into a punching tip well 103.
The punching tip 120 is detachably inserted into the punching tip well 102, and the lower surface of the punching tip 120 is provided with a sharp tip so that the punching tip 120 is configured to punch (perforate) at least one sealing portion among a sealing portion 104b that covers the upper portion of the moisture absorption pad well 104, a sealing portion 105b that covers the upper portion of the reaction well 105, a sealing portion 106b that covers the upper portion of the first washing well 106, a sealing portion 107b that covers the upper portion of the second washing well 107, a sealing portion 108b that covers the upper portion of the third washing well 108, and a sealing portion 109b that covers the upper portion of the fourth washing well 109.
Before being mounted on the multiple biomarker simultaneous analysis apparatus 200 and analysis is performed, the sample well 101, the other wells 104 through 109 except for the sample well 101, the tip well 102, and the punching tip well 103 are sealed by the sealing portions 104b through 109b so as to prevent deterioration or deterioration of performance through reaction with external moisture and air, and analysis of the sample S may be performed by punching the sealing portion using the punching tip 120.
A punching tip coupling hole 120a for coupling with a tip coupling portion 220 is formed at the rear end of the punching tip 120, and the tip coupling portion 220 is inserted into the punching tip coupling hole 120a so that coupling between the tip coupling portion 220 and the punching tip 120 may be made.
The moisture absorption pad well 104 is provided with a moisture absorption pad 104a. A sponge may be applied as the moisture absorption pad 104a. However, if the moisture absorption pad 104a is made of a material capable of absorbing moisture, the material of the moisture absorption pad 104a is not particularly limited thereto.
The moisture absorption pad well 104 is a portion into which the tip 110 is inserted after supporting the sample S, supporting a reaction sample 105c and supporting a washing solution of the tip 110, and as the tip 110 is inserted into the moisture absorption pad well 104, moisture or other unreacted biological material remaining on the lower surface of the tip 110 is removed. Thus, when light is radiated by the optical unit 230, clearer light receiving sensitivity may be achieved.
The reaction sample 105c is stored in the reaction well 105. The reaction sample 105c includes a first binding material 105a that is specifically bound to the detection target material T, like the binding materials coupled to the lower surface of the tip 110. A marker R is bound to the first binding material 105a, and the marker R may include a radioactive isotope, a fluorescent dye, or another type of labeling material. As the marker R is coupled to the first binding material 105a, the optical unit 230 radiates light toward the tip 110, and the presence of the detection target material T included in the sample S and the amount of the detection target material T included in the sample S may be determined using the intensity of light generated by the marker R. A detailed description thereof will be provided later.
Washing solutions 106a through 109a are stored in the washing wells 106 to 109, respectively. The washing well may be one, but may be provided with two or more, and is not particularly limited thereto.
The washing solutions 106a through 109a may include distilled water and buffers other than distilled water depending on the characteristics of the detection target material T to be detected, and different types of distilled water and buffers other than distilled water may be independently stored in different washing wells 106 to 109.
In one embodiment of the present disclosure, the buffers other than distilled water may include a PBS-based solution, more specifically, a mixed solution of Na2HPO4, KH2PO4, NaCl, C58H11-026 solution (Tween-20), and 5-chloro-2-methyl-1,2-thiazol-3-one solution (Proclin 300). The cartridge 100 according to an embodiment of the present disclosure includes buffers other than distilled water, so that unreacted biological material remaining on the lower surface of the tip 110 may be more effectively removed, thereby improving the accuracy of analysis.
A tag capable of specifying a specimen from which the sample S has been collected may be printed on the outer surface of the cartridge 100, and analysis may be performed by specifying the specimen from which the sample S has been collected through the process of recognizing the tag. Thus, the analysis result of the cartridge 100 may be processed, stored, and output by matching the specimen specified by tag recognition.
Next, the multiple biomarker simultaneous analysis apparatus 200 according to an embodiment of the present disclosure will be described in detail with reference to
The multiple biomarker simultaneous analysis apparatus 200 is equipped with the cartridge 100 described above, performs analysis of the sample S injected into the cartridge 100, and determines whether the detection target material T is present in the sample S.
Referring to
The cartridge mounting portion 210 is formed with a seating portion 211 on which the cartridge 100 is placed. The number of seating portions 211 formed in the cartridge mounting portion 210 may be one, but it is also possible to have two or more, and
One cartridge 100 may be installed in one seating portion 211, and in the case of the cartridge mounting portion 210 in which a plurality of seating portions 211 are formed, a plurality of cartridges 100 may be analyzed at a time. A detailed description thereof will be provided later.
The cartridge mounting portion 210 is movable by the cartridge mounting portion moving portion.
Specifically, the cartridge mounting portion 210 is installed while being spaced apart from a bottom surface 201 of the multiple biomarker simultaneous analysis apparatus 200 by a predetermined distance, and the cartridge mounting portion support 212 is formed between the bottom surface 201 and the cartridge mounting portion 210 so that the cartridge mounting portion 210 may be supported.
A first moving rail 201a for movement of the cartridge mounting portion 210 is formed on the bottom surface 201, and the cartridge mounting portion support 212 is coupled to the first moving rail 201a so as to move along the first moving rail 201a.
In addition, the cartridge mounting portion support 212 is connected to a rotation shaft of a first driving motor 213 that provides a driving force for the movement of the cartridge mounting portion 210, and when the rotation of the first driving motor 213 is made, the cartridge mounting portion support 212 is movable along the first moving rail 201a.
The moving direction of the cartridge mounting portion 210 according to the rotation of the first driving motor 213 may be a direction parallel to the ground. However, embodiments of the present disclosure are not limited thereto, and it is also possible for the cartridge mounting portion 210 to move in the left and right directions while forming a predetermined angle with respect to the ground.
The tip coupling portion 220 is coupled to the tip 110 and the punching tip 120 described above. More specifically, the tip coupling portion 220 is inserted into the tip coupling hole 110a formed at the rear end of the tip 110, thereby being coupled to the tip 110. In addition, the tip coupling portion 220 is inserted into the punching tip coupling hole 120a formed at the rear end of the punching tip 120, thereby being coupled to the punching tip 120.
The tip coupling portion 220 is installed in such a way that a part of the front end of the tip coupling portion 220 is exposed to the outside and the other part that is not exposed is inserted into the tip coupling portion mounting base 270.
The mounting base support portion 280 is coupled to the outside of the tip coupling portion mounting base 270.
In the multiple biomarker simultaneous analysis apparatus 200, a second moving rail 281 for movement of the mounting base support portion 280 is extended in a vertical direction, and the mounting base support portion 280 is coupled to the second moving rail 281 so as to move along the second moving rail 281.
In addition, the mounting base support portion 280 is connected to a rotation shaft of a second driving motor 282 that provides a driving force for movement of the mounting base support portion 280, and when the second driving motor 282 rotates, the mounting base support portion 280 is movable along the second moving rail 281.
When the mounting base support portion 280 moves, the tip coupling portion mounting base 270 coupled to the mounting base support portion 280, and the tip coupling portion 220 installed on the tip coupling portion mounting base 270 also move together, and the movement direction of the mounting base support portion 280 according to the rotation of the second driving motor 282 may be a direction perpendicular to the ground. However, embodiments of the present disclosure are not limited thereto, and it is also possible to move the mounting base support portion 280 in the vertical direction while forming a predetermined angle with respect to the ground.
That is, the moving direction of the tip coupling portion 220 may be perpendicular to the moving direction of the cartridge 100.
The tip coupling portion moving portion 260 for moving the tip coupling portion 220 may be formed in the mounting base support portion 280. Referring to
The first tip coupling portion moving portion 261 is a portion for rotational movement of the tip coupling portion 220.
The first tip coupling portion moving portion 261 is coupled to the tip coupling portion mounting base 270 while passing through the mounting base support portion 280 from both sides of the mounting base support portion 280.
The first tip coupling portion moving port 261 formed on both sides of the mounting base support portion 280 each include a third driving motor (not shown), and as the third driving motor (not shown) rotates, the tip coupling portion mounting base 270 coupled thereto may be rotated.
When the tip coupling portion mounting base 270 rotates, the tip coupling portion 220 installed here also rotates together, and more specifically, the tip coupling portion 220 may be rotated from a position perpendicular to the ground to a position parallel to the ground.
When the tip coupling portion 220 is rotated to the position parallel to the ground by rotation of the third driving motor (not shown), the lower surface of the tip 110 coupled to the tip coupling portion 220 is located on an optical path on which light is radiated by the optical unit 230. Thus, because analysis is performed in a state in which the lower surface of the tip 110 is exposed to outside air instead of in a state supported on a sample or reagent, interference by external factors such as contamination and residues is not made. Thus, a more accurate optical signal may be detected.
The second tip coupling portion moving portion 262 is a portion for vibrating the tip coupling portion 220 in the vertical direction.
The second tip coupling portion moving portion 262 is installed on one side of the mounting base support portion 280. To this end, a mounting groove 283 having a length longer than the length of the second tip coupling portion moving portion 262 is formed in the mounting base support portion 280.
The second tip coupling portion moving portion 262 is coupled to a rotation shaft of the fourth driving motor 263 installed to face the mounting base support portion 280 interposed therebetween, and when the rotation of the fourth driving motor 263 is made, the second tip coupling portion moving portion 262 may vibrate in the vertical direction along the mounting groove 283.
In other words, the vertical length of the mounting groove 283 is longer than the vertical length of the second tip coupling portion moving portion 262, and the mounting base support portion 280 can vibrate in the vertical direction by using a difference between the vertical length of the mounting groove 283 and the vertical length of the second tip coupling portion 262 as an amplitude.
When the mounting base support portion 280 vibrates in the vertical direction, the tip coupling portion mounting base 270 coupled to the mounting base support portion 280, and the tip coupling portion 220 installed in the tip coupling portion mounting base 270 vibrate in the vertical direction.
The tip 110 may vibrate in the vertical direction with a predetermined amplitude in the well by vibration in the vertical direction. Thus, reaction between the binding materials coupled to the lower surface of the tip 110 and the detection target material, reaction between the detection target material T and the binding material in the reaction sample 105c, and the washing of the unreacted biological material remaining on the lower surface of the tip 110 may be performed more effectively.
The optical unit 230 includes a radiator for radiating light toward the outside, and a receiving portion for receiving the light entering the inside.
The tip coupling portion 220 is rotated by the first tip coupling portion moving portion 261, and the tip 110 coupled to the tip coupling portion 220 is rotated together.
At this time, the lower surface of the tip 110 is located on the optical path on which light is radiated by the optical unit 230. For example, a binder bound in the order of the first bonding material, the detection target material, and the second bonding material is located on the lower surface of the tip 110. Here, the marker R such as a radioactive isotope, fluorescent material, etc., is bound to the first binding material, and the first binding material generates a specific optical signal according to the type of the marker R by light radiation of the optical unit 230.
The optical unit 230 may receive the specific optical signal, and the processing unit 240 determines the presence of the detection target material T in the sample S and the amount of the detection target material T included in the sample S according to the intensity of the received optical signal.
An intermediate portion 231 through which a through hole 231 is formed, is further formed between the optical unit 230 and the tip coupling portion 220.
The number of through holes 231a may be the same as the number of seating portions 211 formed in the cartridge mounting portion 210, and the intermediate portion 231 having six through holes 231a formed therein is shown in
The light radiated by the optical unit 230 passes through the through hole 231a of the intermediate portion 231, and the optical signal generated on the lower surface of the tip 110 according to the light radiation also passes through the through hole 231a and is received by the optical unit 230.
Only the optical signal passing through the through hole 231a is received by the optical unit 230, and as analysis is performed using the received optical signal, interference caused by light incident from the outside may be minimized.
The optical unit 230 is installed to be spaced apart from the bottom surface 201 by a predetermined distance, and an optical unit support 232 is installed between the bottom surface 201 and the optical unit 230, and the optical unit support 232 is movable along the third moving rail 233 in a direction parallel to the ground. To this end, the optical unit support 232 is coupled to a fifth driving motor 234, so that the optical unit support 232 may move along the third moving rail 233 according to the rotation of the fifth driving motor 234.
More specifically, the optical unit 230 is movable when the optical unit 230 and the through hole 231a are aligned with each other so that light radiated from the optical unit 230 passes through the through hole 231a formed in the intermediate portion 231. All of the plurality of tips 110 coupled to the plurality of tip coupling portions 220 may be analyzed according to the movement of the optical unit 230.
The moving direction of the multiple biomarker simultaneous analysis apparatus 200 according to an embodiment of the present disclosure is summarized as follows.
As shown in
The processing unit 240 determines whether the detection target material T is present in the sample S injected into the cartridge 100 using the light received by the optical unit 230 and the amount of the detection target material T included in the sample S.
The processing unit 240 may be a microprocessor (MCU) or a computer having data operation and processing functions, but is not particularly limited thereto as long as the processing unit 240 has data operation and processing functions.
When the detection target material T is present in the sample S, the detection target material T is specifically bound to the binding material formed on the tip 110, and the detection target material T is also specifically bound to the binding material contained in the reaction sample 105c.
Thus, a binder bound in the order of the first binding material, the detection target material, and the second binding material is formed. A marker R, such as a radioactive isotope, a fluorescent material, etc. is bound to the first binding material, and the first binding material generates a specific optical signal by light radiation.
When the detection target material T is included in the sample S, a specific optical signal may be received by the optical unit 230 by light radiation, and the processing unit 240 may determine the presence or absence of the detection target material T in the sample S and the amount of the detection target material T contained in the sample S using the positions of different binding materials coupled to the lower surface of the tip 110 and the intensity of the optical signal at the corresponding positions.
In addition,
The processing unit 240 may determine that the detection target material of CA19-9, AFP, CEA, PSA and CA125 is present in the corresponding sample, but may determine that AFP and CEA are more than PSA and CA125, and that CA19-9 is less than PSA and CA125.
In
The processing unit 240 may determine that CA19-9 is not present in the corresponding sample, and may determine that AFP, CEA, PSA, and CA125 are present, but the processing unit 240 may determine that AFP and CEA are more than PSA and CA125. Also, the processing unit 240 may determine that the amounts of AFP and CEA in the corresponding sample of
As such, in the multiple biomarker simultaneous analysis apparatus 200 according to an embodiment of the present disclosure, multiple biomarkers are coupled to one tip 110, and an optical signal at a position where a corresponding biomarker is coupled to the tip 110, is analyzed so that the presence or absence of the biomarker in the sample S may be determined.
In addition, in the multiple biomarker simultaneous analysis apparatus 200 according to an embodiment of the present disclosure, a plurality of cartridges 100 may be placed in one cartridge mounting portion 210, and the presence or absence of a biomarker in the sample S for a plurality of specimens may also be determined in one analysis operation.
Hereinafter, a multiple biomarker simultaneous analysis method using the multiple biomarker simultaneous analysis apparatus 200 will be described in detail with reference to
First, the cartridge 100 is installed on the seating portion 211 of the cartridge mounting portion 210.
Next, the sample S is injected into the sample well 101 of the cartridge 100 (

Next, the tip coupling portion 220 and the punching tip 120 are separated, and the first driving motor 213 rotates so that the cartridge mounting portion 210 moves along the y-axis direction to combine the tip well 102 and the tip. The portions 220 are aligned in a vertical direction (
Next, the second driving motor 282 rotates so that the mounting base support portion 280 moves downward along the z-axis direction, and the tip 110 provided in the tip well 102 and the tip coupling portion 220 are coupled to each other (

Next, the second driving motor 282 rotates so that the mounting base support portion 280 moves downward along the z-axis direction, and the tip 110 coupled to the tip coupling portion 220 is supported on the sample S of the sample well 101 (
In this process, the detection target material T included in the sample S and the binding material that is specifically bound to the detection target material T and coupled to the lower surface of the tip 110 are bound.
In addition, in this process, the fourth driving motor 263 rotates, and accordingly, the mounting base support portion 280, the tip coupling portion mounting base 270, and the tip coupling portion 220 vibrate in the vertical direction with a predetermined amplitude.
That is, as the lower surface of the tip 110 vibrates in the vertical direction while being supported on the sample S, the binding material coupled to the lower surface of the tip 110 and the detection target material T contained in the sample S may be effectively bound. However, the vertical vibration movement of the tip coupling portion 220 is not essential, and this process may be omitted.
Next, the first driving motor 213 rotates so that the cartridge mounting portion 210 moves along the y-axis direction, and the reaction well 105 and the tip coupling portion 220 are aligned in a line in the vertical direction.

In this process, the unreacted biological material remaining on the lower surface of the tip 110 may be washed by the washing solution 106a, and as a result of the washing, for example, only a first binding material—detection target material—second binding material binder may be bound to the lower surface of the tip 110. Thus, the problem of inaccurate analysis due to the occurrence of interference of the optical signal due to the unreacted biological material is prevented.
In this process, the fourth driving motor 263 rotates, and accordingly, the mounting base support portion 280, the tip coupling portion mounting base 270, and the tip coupling portion 220 vibrate in the vertical direction with a predetermined amplitude.

Next, the tip coupling portion mounting base 270 is rotated according to the rotation of the third driving motor (not shown), and accordingly, the lower surface of the tip 110 is located on the optical path on which light is radiated by the optical unit 230.
Next, the optical unit 230 radiates light toward the lower surface of the tip 110, and a specific optical signal generated as the radiated light reaches the marker R, is received by the optical unit 230 (
Next, the processing unit 240 may determine the presence of the detection target material T, for example, corresponding to a portion of the tip 110 having an intensity greater than or equal to a predetermined intensity level using the intensity of the optical signal received by the optical unit 230, and further, may determine the amount of the detection target material T.
When a multiple biomarker simultaneous analysis apparatus of the present disclosure is used, analysis errors caused by components other than a sample can be minimized through a process in which a detection target material is coupled to the lower end of a tip and moves, so that time and cost required for a detection process of the detection target material can be reduced.
Furthermore, as compared to an analysis apparatus according to the related art that detects an optical signal generated within a well of a cartridge, in the analysis apparatus according to the present disclosure, an optical signal generated at the tip outside the well of the cartridge can be detected. Accordingly, in the analysis apparatus according to the present disclosure, because the optical signal is less or not subject to complete interference by external factors such as contamination and residues, a more accurate optical signal can be detected.
