Claims
- 1. A method for printing a microarray comprising:
providing a substrate having a substrate surface; providing at least one probe reservoir; providing at least one capillary bundle comprising a plurality of individual capillaries; each of the capillaries having an input end and an output end; wherein the output ends of the individual capillaries are secured in a print head such that the output ends of the capillaries are substantially coplanar in an array in a facet of the print head such that the capillaries have a capillary pitch P; placing the input ends of the individual capillaries in fluid communication with at least one probe reservoir; transporting probe from at least one probe reservoir to the output ends of the capillaries; and printing an array of probes on the substrate such that the printed probes have a probe pitch of approximately PIN; wherein N is an integer greater than one.
- 2. The method of claim 1 wherein printing an array of probes further includes the step of printing the array of probes in N2 number of separate prints.
- 3. A method for printing a microarray, comprising:
providing a substrate for receiving a probe array having a probe pitch p; providing at least one probe reservoir; providing at least one capillary bundle comprising a plurality of individual capillaries; each of the capillaries having an input end and an output end; wherein the output ends of the individual capillaries are secured in a print head such that the output ends of the capillaries are substantially coplanar in an array in a facet of the print head such that the capillaries have a capillary pitch P; wherein the capillary pitch P is an integer multiple of the probe pitch p; wherein the integer is greater than one; placing the input ends of the individual capillaries in fluid communication with at least one probe reservoir; transporting probe from the at least one probe reservoir to the output ends of the capillaries; and printing N2 number of prints to deposit N2 sets of probes onto the substrate to form a probe array having a probe pitch p.
- 4. A method for printing a microarray comprising:
providing a substrate having a substrate surface; providing at least one reservoir; providing at least one print head comprising a plurality of fluid dispensing members having a distal end and a proximal end; each fluid dispensing member being in fluid communication with at least one reservoir; wherein the proximal ends of the individual fluid dispensing members are secured such that the proximal ends of the fluid dispensing members are substantially coplanar in an array in a facet of the print head; printing a first array of first material onto the substrate; and printing at least a second array of at least second material onto the first array.
- 5. A method for printing a microarray using at least one capillary bundle comprising a plurality of individual capillaries, each of the capillaries having an input end and an output end, wherein the output ends of the individual capillaries are secured in a print head, said method comprising:
transporting probe from at least one probe reservoir to the output ends of the capillaries; printing a first array of probes on a substrate; and printing a second array of probes on the substrate, said second array of probes overlapping and offset from the first array of probes such that at least some of the probes in the second array of probes are located between the probes in the first array of probes.
- 6. A method of associating proximal and distal ends of a plurality of capillaries in a capillary bundle, said method comprising:
loading a plurality of fluids into the distal ends of the plurality of capillaries, each capillary having a unique fluid being loaded therein; transporting the plurality of fluids from the distal ends of the plurality of capillaries to the proximal ends; printing the plurality of fluids from the proximal ends of the plurality of capillaries onto a substrate to form an array of spots, each spot corresponding to one of the plurality of fluids; and registering one of the capillaries by identifying the fluid forming one of the spots in the array of spots, matching the identified fluid with one of the plurality of fluids loaded into the distal ends of the capillaries, and correlating the location of the spot with the capillary loaded with the matched fluid.
- 7. The method of claim 6, wherein said loading a plurality of fluids into the distal ends of the plurality of capillaries comprises:
loading a plurality of fluids into the distal ends of the plurality of capillaries, each fluid including a unique combination of one or more oligonucleotides, each of the one or more oligonucleotides having a known sequence.
- 8. The method of claim 7, wherein said identifying the fluid forming one of the spots in the array of spots comprises:
hybridizing the array of spots with a target solution including targets complimentary to one of the oligonucleotides in the unique combination of one or more oligonucleotides.
- 9. The method of claim 7, wherein said loading the plurality of fluids into the distal ends of the plurality of capillaries comprises:
loading a plurality of fluids into the distal ends of the plurality of capillaries, each fluid including: (1) a reference oligonucleotide having a known sequence; and (2) the unique combination of one or more oligonucleotides.
