Paper Abstract

Thin polymer films provide a convenient matrix in which to support a variety of indicator molecules that are distinguished by their ability to modulate light signals when exposed to specific analytes of interest. Using this general idea, sensors have been developed from both planar waveguides and optical fibers in conjunction with thin polymer films for a variety of process monitoring and control applications. Most of these have been concerned with pH and dissolved oxygen, but many other compounds can be similarly detected. In order to better understand the sensing process, theoretical models are developed in this paper starting from a rigorous analysis of the underlying chemical and physical processes. The validation of the model for a variety of systems is shown.
