Abstract: Presented are encoded microparticles, methods of use in biological assays, and flexible, modular instrument systems for conducting a variety of biological assays using the encoded microparticles. The systems include various instrumentation components which are exchangeable and offer a single flexible platform on which a large number of different types of experiments and assays may be conducted including, for example, microarray analysis, encoded microparticle single and multiplex detection, tissue dissection and isolation, and other genetic analysis techniques.

Abstract: A system and method for encoded microparticles is described. One embodiment includes an encoded microparticle comprising a plurality of segments, wherein the plurality of segments form a spatial code; contrast coating on at least one segment of the plurality of segments, wherein the contrast coating further encodes the microparticle; an outer surface, wherein the outer surface encloses the spatial code and contrast coating, and wherein the spatial code and contrast coating are detectable through the outer surface.
