Abstract

A cell capture system including an array, an inlet manifold, and an outlet manifold. The array includes a plurality of parallel pores, each pore including a chamber and a pore channel, an inlet channel fluidly connected to the chambers of the pores; an outlet channel fluidly connected to the pore channels of the pores. The inlet manifold is fluidly connected to the inlet channel, and the outlet channel is fluidly connected to the outlet channel. A cell removal tool is also disclosed, wherein the cell removal tool is configured to remove a captured cell from a pore chamber.

Claims (28)

1. A method comprising:

providing a substrate comprising:

a sample inlet coupled to an inlet manifold,

an outlet manifold,

a set of inlet channels connected to the inlet manifold,

a set of outlet channels connected to the outlet manifold, and

a set of chambers in fluid communication with an inlet channel of the set of inlet channels and an outlet channel of the set of outlet channels, the inlet channel paired with the outlet channel, wherein flow from the inlet manifold is configured to reach the outlet manifold only by passing into the set of chambers;

receiving a sample into the sample inlet;

sealing the substrate; and

performing a set of processes upon the sample within the set of chambers at the substrate.

2. The method of claim 1 , wherein the set of chambers comprises from 100 to 1,000,000 individual chambers.

3. The method of claim 1 , wherein the sample comprises a bodily fluid.

4. The method of claim 1 , wherein the sample is derived from blood.

5. The method of claim 1 , wherein receiving the sample into the sample inlet with application of positive pressure.

6. The method of claim 1 , wherein sealing the substrate comprises using a top layer to form a fluid impermeable seal with the substrate.

7. The method of claim 1 , wherein sealing the substrate comprises sealing with a polymeric laminate.

8. The method of claim 1 , wherein receiving the sample comprises pumping the sample from the inlet channel to the outlet channel by a pumping system.

9. The method of claim 1 , wherein performing the set of processes upon the sample comprises performing a nucleic acid analysis.

10. The method of claim 1 , wherein flow reaches chambers of the set of chambers sequentially.

11. The method of claim 1 , wherein the set of processes comprises a polymerase chain reaction (PCR) process.

12. The method of claim 11 , further comprising delivering PCR reagents into the set of chambers for the PCR process.

13. The method of claim 1 , wherein the set of processes further comprises a thermocycling process with transmission of heat to the substrate by way of a thermal control system.

14. The method of claim 1 , wherein the set of processes comprises an optical detection process configured for detecting signals derived from the set of chambers.

15. The method of claim 14 , wherein the optical detection process comprises detecting emitted light from the set of chambers.

16. The method of claim 15 , wherein detecting emitted light comprises transmitting light to the substrate by way of an illuminator and detecting fluorescence from the set of chambers.

17. The method of claim 1 , wherein the set of processes comprises sample processing for a proteomic analysis.

18. The method of claim 1 , wherein the set of processes comprises sample processing for at least one of nucleic acid analysis and genomic sequencing.

19. The method of claim 1 , wherein the set of processes comprises cell counting.
