ABSTRACT
A fiber-optic sensor has been prepared which responds to carbon dioxide at physiologically significant concentrations. It is based on pH modulation by dissolved carbon dioxide in a sensing layer of fluorescent dye. By use of a previously developed methodology by which the sensing chemistry is bonded directly to the glass fiber tip, the miniature size of the sensor is preserved. This method involves consecutive applications of solution polymers to the fiber tip rather than mechanical attachment of sensor reagents. Preparations of polymer-immobilized dyes and polymer membranes are described.
