    Notes: A new ferrocene derivative was synthesized by reacting hydroxymethylferrocene with anthracene-9-carboxylic acid. This new compound strongly adsorbs on the surface of a graphite electrode to form a stable chemically modified electrode. The formal potential of the adsorbed ferrocene derivative was +340 mV versus SCE in solutions containing 0.1 M perchlorate. When adsorbed, the ferrocene derivative mediates the charge transfer between the electrode and glucose oxidase.

    An electrochemical sensor for hydrogen peroxide based on peroxidase adsorbed on a spectrographic graphite electrode (1989)

    Notes: Horse-radish peroxidase was found to strongly adsorb on the surface of spectrographic graphite with retained catalytic activity. Efficient electron transfer from the graphite to the oxidized form of adsorbed peroxidase could be achieved without the deliberate addition of a mediator. The peroxidase-modified graphite was used as a sensor for hydrogen peroxide in a flow-injection system. Response currents to hydrogen peroxide start at +600 mV vs. SCE and reach a maximal value at -200 mV. Highest activities were found between pH 4 and 6. Linear calibration curves for hydrogen peroxide were obtained from 0.1 to 500 μM with an injection volume of 50 μL.
