Abstract:
The use of focused, high intensity light from a sapphire laser generating femtosecond pulses is discussed. The pulses are used to create a topographical structure in a flat surface of polydimethylsiloxane. The use of these surfaces patterned by this procedure is also discussed. The technique permits non-photolithographic generation of surface topography for use in soft lithography and microfluids.
