Abstract

The distal tip of a 350-micrometers imaging fiber comprised of thousands of 4- to 6-micrometers fibers is coated with a thin layer of pH sensitive material. Polymerization is initiated photochemically and is combined with spin coating techniques to yield a uniform coating of polyHEMA/fluorescein on the order of 10 micrometers thick. Performance data for this fiber demonstrates it is capable of simultaneous pH measurements and near-field imaging.
