Abstract
A multilayer integrated assembly for effecting fluid handling functions includes complementary microstructures formed by an etching or similar process in a planar foldable substrate. The complementary microstructures may be superimposed in a controlled manner by operation of micro-alignment means also formed in the foldable substrate by an etching or similar process. Microstructures are contemplated as including channels (that may be superimposed to form fluid conduits), apertures, conduit apertures, sample processing compartments, and the like. The resulting integrated assembly may be bonded and subsequently operated to implement one or more fluid-handling functions.
