Abstract

The distal tip of a 200 micrometers imaging fiber comprised of thousands of 2 micrometers fibers is coated with a thin layer of pH sensitive material. Polymerization is initiated thermally, and results in 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.
