1. A system for cell retrieval, comprising:
- a cell capture substrate comprising a first broad face and second broad face opposing the first broad face, the cell capture substrate defining;
a substrate body bounded by a plane, the plane coplanar with the first broad face;
a set of wells within the substrate body, each well of the set defining;
an aperture at the plane;
a base arranged between the aperture and the second broad face; and
a wall extending from the aperture to the base; and
a plurality of channels defined within the substrate body, wherein each well of the set is fluidly coupled to an adjacent well of the set by a respective channel of the plurality;
an imaging subsystem configured to sample image data of a target well of the set;
a cell retriever subsystem comprising;
a cell extractor comprising an extractor tip and an outlet, wherein;
the cell extractor defines a void between the extractor tip and the outlet; and
the extractor tip is positioned proximal the plane; and
a pump fluidly coupled to the void via the outlet;
an actuator configured to translate the cell extractor with respect to the cell capture substrate along an axis substantially normal the plane, the actuator operable to place the extractor tip for fluid communication with the target well; and
a control subsystem configured to;
receive the image data from the imaging subsystem;
based on the image data, control a motor of the actuator to position the extractor tip for fluid communication with the target well; and
in response to achieving positioning of the extractor tip for fluid communication with the target well, control the cell retriever to extract a cell from the target well.

Abstract
A system and method for isolating and analyzing single cells, including: 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.
