Abstract

A system and method for isolating and analyzing single cells, comprising: a substrate having a broad surface; a set of wells defined at the broad surface of the substrate, and a set of channels, defined by the wall, that fluidly couple each well to at least one adjacent well in the set of wells; and fluid delivery module defining an inlet and comprising a plate, removably coupled to the substrate, the plate defining a recessed region fluidly connected to the inlet and facing the broad surface of the substrate, the fluid delivery module comprising a cell capture mode.

Claims (34)

1. A system for isolating and analyzing a population of target particles from a biological sample in single-particle format, the system comprising:

a substrate having a broad surface, wherein the substrate defines an inlet and a set of wells in fluid communication with and downstream of the inlet, the set of wells arranged in a hexagonal close-packed configuration,

wherein each well in the set of wells is configured to receive and retain a target particle of the population of target particles and comprises:

a base surface defined within the substrate,

an open surface directly opposing the base surface, and

a well cavity defined by the base surface and the open surface, the well cavity having a longitudinal axis arranged normal to a flow direction from the inlet and across the open surface, and

wherein the substrate defines the set of wells at a region having a total surface area of at least 144 square millimeters, and wherein the set of wells comprises at least 250,000 individual wells within the total surface area; and

a cavity configured to provide a boundary of a fluid layer adjacent to the well cavities of the set of wells.

2. The system of claim 1 , wherein the well cavity defines a prismatic volume.

3. The system of claim 2 , wherein the prismatic volume comprises a hexagonal prismatic volume.

4. The system of claim 1 , wherein each well further comprises a set of walls extending between the base surface and the open surface, wherein each wall in the set of walls has a wall thickness that is equal to or less than five microns.

5. The system of claim 4 , wherein the set of walls of at least one well defines a hexagonal footprint about the base surface of the at least one well.

6. The system of claim 1 , wherein the open surface of at least one well in the set of wells defines a characteristic dimension that is less than 50 microns.

7. The system of claim 1 , further comprising a fluid delivery subsystem comprising a manifold configured to interface with the inlet of the substrate and the open surfaces of the set of wells.

8. The system of claim 7 , wherein the fluid delivery subsystem further comprises a delivery inlet and an outlet fluidly coupled by and arranged on opposing sides of the fluid layer, and wherein the delivery inlet and the delivery outlet are fluidly coupled to a flow control subsystem operable in a flow mode that applies one of a positive pressure gradient and a negative pressure gradient between the delivery inlet and the delivery outlet.

9. The system of claim 7 , wherein the fluid delivery subsystem comprises an upper plate reversibly coupleable to the substrate, wherein the upper plate spans at least a portion of the broad surface of the substrate, and is arranged superior to the set of wells.

10. The system of claim 9 , wherein the upper plate comprises a recess facing the broad surface of the substrate and, upon attaching the upper plate to the substrate, the recess and the broad surface cooperatively defining the cavity adjacent to the well cavities of the set of wells.

11. The system of claim 1 , further comprising a thermal control subsystem comprising a heating plate abutting the cavity and promoting convective flow in the flow direction, upon heating of the fluid layer during operation.

12. The system of claim 11 , wherein the heating plate seals the cavity adjacent to the well cavities of the set of wells.

13. The system of claim 1 , wherein the population of target particles comprises a population of viable rare cells, and wherein the system is configured to provide flow through the fluid layer for transmission of captured rare cells, from the set of wells, in a viable state.

14. The system of claim 1 , wherein the set of wells comprise a plurality of subsets of wells, wherein the wells in the subset of wells are fluidly connected to one another by a set of fluidic channels.

15. The system of claim 14 , wherein each subset of wells includes six peripheral wells arranged about a central well within the plane of the broad surface of the substrate, and wherein each peripheral well is fluidly connected to the central well.

16. A system for isolating and analyzing a population of target particles in single-particle format, the system comprising:

a substrate having a broad surface, wherein the substrate defines an inlet and a set of wells in fluid communication with and downstream of the inlet, the set of wells arranged in a close-packed configuration,

wherein each well in the set of wells is configured to receive and retain a target particle of the population of target particles and comprises:

a base surface defined within the substrate,

an open surface directly opposing the base surface, and

a well cavity defined by the base surface and the open surface, the well cavity having a longitudinal axis arranged normal to a flow direction from the inlet and across the open surface, and

wherein the set of wells comprises at least 250,000 individual wells configured to collectively receive from 0.1 to 10 milliliters of fluid; and

a cavity configured to provide a boundary of a fluid layer adjacent to the well cavities of the set of wells.

17. The system of claim 16 , wherein the well cavity defines a hexagonal prismatic volume.

18. The system of claim 16 , wherein the open surface of at least one well in the set of wells defines a characteristic dimension that is less than 50 microns.
