AN AMPEROMETRIC BIOSENSOR FOR HYDROGEN PEROXIDASE BASED ON THE CO-IMMOBILIZATION OF CATALASE AND METHYLENE BLUE IN AN AL2O3 SOL-GEL MODIFIED ELECTRODE

Two Divisions of the International Union of Pure and Applied Chemistry (IUPAC), namely Physical Chemistry (Commission 1.7 on Biophysical Chemistry formerly Steering Committee on Biophysical Chemistry) and Analytical Chemistry (Commission V. 5 on Electroanalytical Chemistry) have prepared recommendations on the definition, classification and nomenclature related to electrochemical biosensors; these recommendations could, in the future, be extended to other types of biosensors.
