Patent ID: 8569046

Claim:
A microarray formed in a planar surface of a moldable slab, the microarray comprising: a plurality of microchannels formed in the planar surface of the moldable slab, the plurality of microchannels being configured to form a lattice that defines a plurality of interlineal regions; and a plurality of microwell sets, each of which is positioned in one of the interlineal regions, wherein each set comprises a plurality of microwells formed in the planar surface of the moldable slab, and each microwell is sized to contain at least a single cell, wherein the microchannels and microwells are arranged and constructed in the planar surface of the moldable slab such that, when the planar surface of the moldable slab is placed in contact with a planar surface of a substrate such that a seal is formed between the moldable slab and the substrate, liquid on the planar surface of the moldable slab is excluded from an interfacial region, via the microchannels.
