Abstract:

The present invention provides systems and methods for data acquisition and image analysis that utilize twisted nematic liquid crystals (“TNLCs”) to create maps of bio/chemical functionality patterned on surfaces. The method involves the acquisition of a series of images of TNLC film that contacts the analytic surface followed by analysis of the series of images to yield maps of twist angle of the liquid crystal across the surface. This analysis technique effectively condenses a large data set (stack of images) into a compact form (map of twist angle), revealing features on the surface that were not apparent in the individual images comprising the original stack.
