Abstract:
1. A microfluidic device structure, comprising: a first, base ply provided with at least one microscale recess fabricated in an upper surface thereof, said at least one microscale recess at least partly defining a sealing channel; at least one molded in situ member selected from the group consisting of a seal and a seal and channel lining, which is molded in situ in said sealing channel and projects above said upper surface of said base ply; and a secondary substrate having a lower surface in sealing contact with said at least one molded in situ member, said base ply and said secondary substrate defining sandwich layers, wherein said upper surface of said base ply is spaced apart from said lower surface of said secondary substrate, and wherein said at least one molded in situ member forms at least one containment surface and wherein said at least one molded in situ member, said upper surface of said base ply and said lower surface of said secondary substrate together define and seal closed a microfluidicly active volume therebetween with microfluidic functionality which volume is in the form of at least one member selected from the group consisting of a fluid channel, a chamber portion, and a fluid channel and chamber portion.
