ABSTRACT:
Enzyme electrodes are disclosed consisting essentially of a uniform homogeneous layer of a finely divided platinum group metal or oxide, preferably preadsorbed onto the surface of an activated carbon or grapite powder, and deposited from suspension upon the surface of an electrically conductive substrate and in admixture with an enzyme and optionally a water soluble or water-dispersible binder. Preferably the enzyme electrodes are produced by coating the substrate with a suspension of the enzyme, the finely divided platinum group metal, and if present the carbon or graphite powder and binder, and drying at a temperature below that at which the enzyme is deactivated.
