Abstract:
A "living" radical photo-polymerization (LRPP) technique is used to rapidly fabricate microfluidic channels and micro-patterned porous polymer monoliths. Surface-initiated LRPP is then used to functionalize porous elements in a robust one-step surface modification process. Assay-ready platforms can be fully realized in less than 30 minutes. An application relevant to clinical diagnostics is presented.
