Optical Sensors on the Basis of a Polyelectrolyte Peroxidase–Chitosan Complex for the Determination of Biologically Active Compounds

Abstract

The review summarizes authors’ works of the last 15 year covering the possibilities, advantages, and prospects for the use of optical sensors based on peroxidase for the determination of a wide range of biologically active compounds, i.e., phenolic compounds and hydroperoxides of different structures, phenothiazines, catecholamines, and their metabolites, for the quality control of drugs, foodstuffs, biomedical research, and clinical diagnostics.
