title: Enzyme electrodes based on organic metals.
abstract: The parameters of enzyme electrodes based on organic metals are presented. Cytochrome b2 (E.C. 1.1.2.3), glucose oxidase (E.C. 1.1.3.4), xanthine oxidase (E.C. 1.2.3.2) and peroxidase (E.C. 1.11.1.7) were used in electrodes sensitive to L-lactate, glucose, hypoxanthine and hydrogen peroxide. Electrocatalytic oxidation of NADH on organic metals and ethanol and acetaldehyde sensitive electrodes containing alcohol dehydrogenase (E.C. 1.1.1.1) were studied. Biocatalytic charge accumulation, the mechanism of electron exchange between the enzyme active centres and organic metals, and the future application of organic metals are discussed.
