Abstract
A color CCD (charge-coupled device) camera is used as a chemical detector to quantify fluorescence emission intensities from two kinds of optofluidic device platforms. the fluorophores responsive to oxygen are immobilized in photo-patternable hydrogel matrices. the first device is a hydrogel sensor array formed within a commercial silicone elastomer imaging chamber. the second one involves a double-chamber fluidic device composed of a permeable membrane layer and dry film photoresist layers. the results suggest that digital color imagers, in combination with a simple color separation method, can serve as the high-quality chemical detectors for fluidic biosensors and biological culture platforms. © 2010 IEEE.
