POLYMETHACRYLATE OPTICAL SENSORS FOR CHEMICAL ANALYSIS

N. Gavrilenko, A. Spiridonova, S. Muravyov

Abstract

Optical chemical sensors usually utilize immobilized reagents in a solid matrix usually in the form of a monolith or a thin film. The reagents immobilized into the sensor are responsible for the extraction of the analyte into the sensing material and generating an optical signal proportional to the change in the concentration of the analyte. In the work presented here we propose to use transparent polymethacrylate matrix (PMM) for physical immobilization of analytical reagents. The using of PMM allowed us to combine the capability of the solid phase to immobilize reagents without losing the matrix transparence and the capability of the reagents to participate in the analytical reaction with analytes accompanied by an optical effect.
