Hydrogen Peroxide has been shown to be efficiently electroreduced at an electrode modified with a hydrophilic, penneable film of horseradish peroxidase covalently bound to a 3-dimensional epoxy network having polyvinyl pyridine (PVP)-complexed [Os(bpy)2Cl] - 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 cm - M"1, and their limiting currents relate to the enzyme s ability to complex with the redox epoxy network. [Pg.180]
