Abstract

A sensor capable of simultaneous imaging and pH measurements has been prepared by coating the distal tip of a single imaging fiber with a pH sensitive material. The coated fiber is fabricated using photochemical polymerization with a spin coating technique, and results in a fairly uniform coating of polyHEMA/fluorescein on the order of 10 micrometers thick. Performance data, and imaging capabilities, as well as instrumentation requirements and deposition chemistry, are discussed.
