Hydrogen peroxide‐sensitive electrode based on horseradish peroxidase‐modified platinized carbon
Abstract
Abstract Elearodes are described based on horseradish peroxidase (HRP) modified platinized carbon particles which are capable of reducing hydrogen peroxide at 0.0 V (vs. SCE). The HRP was covalently attached to the surface of the carbon particles via cyanuric chloride. Energy‐dispersive X‐ray analysis confirmed the presence of cyanuric chloride on the surface of the carbon. Electrochemical studies on these electrodes indicated that they were stable for extended periods and that the bound HRP was capable of mediating the electrocatalytic reduction of hydrogen peroxide.
