Abstract

Gratings are written holographically with low power ( 10 mW / cm 2 ) 244   nm UV light on thin films of polybutadiene rubber polymer. The increase of hydrophilicity–wettability of polybutadiene films is measured over UV-exposed regions. Sequential fabrication of two orthogonal gratings results in hydrophilic microarrays having applications as functionalized substrates for immobilizing biomolecules. This is demonstrated by immobilizing a phospholipid in a microarray pattern.
