Abstract:
1. A microfluidic network comprising: a polymeric structure including therein at least a first and a second non-fluidically interconnected fluid flow paths, with at least the first flow path comprising a series of interconnected channels within the polymeric structure, the series of interconnected channels including at least one first channel disposed within a first level of the structure, at least one second channel disposed within a second level of the structure, and at least one connecting channel fluidically interconnecting the first channel and the second channel, where at least one channel within the structure has a cross-sectional dimension not exceeding about 500 μm, and where the structure includes at least one channel disposed within the first level of the structure that is non-parallel to at least one channel disposed within the second level of the structure.
