Tuning of micropattern features by variations in photomask band sizing, light intensity, photoinitiator concentration, and UV exposure time. A) Feature frequency is controlled by photomask design. Amplitude profiles represent photomasks with periodicities of 100, 50, 33, and 10 μm. Maximum attainable amplitude is limited as periodicity (mask band size) decreases. B) Channel amplitude as a function of varying initiating light intensity and UV exposure time. C) Channel amplitude as a function of photoinitiator concentration as well as UV exposure time. Periodicity for all trials in (B) and (C) is 50 μm. Each point indicates mean±SD.
