Hydrogen Peroxide Electrodes Based on Electrical Connection of Redox Centers of Various Peroxidases to Electrodes through a Three-Dimensional Electron Relaying Polymer Network

Abstract

Hydrogen Peroxide has been shown to be efficiently electro-reduced at an electrode modified with a hydrophilic, permeable film of horseradish peroxidase covalently bound to a 3-dimensional epoxy network having polyvinyl pyridine (PVP)-complexed Os(bpy)2C1+2/+3 redox centers. Four peroxide sensing cathodes based on peroxidases from Arthromyces ramosus, horseradish and bovine milk are compared. Their sensitivity at O.OV (SCE) ranges from 0.1 - 1.0 A sq cm / M, and their limiting currents relate to the enzyme's ability to complex with the redox epoxy network.
