Micropatterns of PEG on PDMS substrates. (A) Optical image of micropatterned channels on 10:1 PDMS with 25 and 50 μm width with 150 μm PEG-DA squares. Selective FITC-BSA adhesion to the channels signified by the green fluorescence and resistance to adhesion by the dark PEG-DA 150 μm squares in (B) (C) Different patterns with features down to 10 μm can be easily patterned via graft polymerization and photolithography (Scale bar = 200 μm).
