Microarray device with elastomeric well structure

A microarray device for testing of biological or pharmaceutical samples, said microarray device comprising a base housing, a rigid transparent bottom plate, and a bottomless elastomeric microarray structure with internal frame, wherein said base housing and said internal frame are mechanically latched together thus forming a specified number of watertight elastomeric microarray reservoir wells such that merely the compressive force generated by a latching interface between said transparent bottom plate and said microarray structure creates a series of water tight seals against said transparent bottom plate.

A method of manufacturing a bottomless elastomeric microarray structure with internal frame, wherein an elastomeric material is over-molded or co-injected onto said internal frame by transfer, compression or injection molding, producing said bottomless elastomeric microarray structure with internal frame.
