COVALENT LINKAGE OF GLUCOSE-OXIDASE TO MODIFIED BASAL-PLANE PYROLYTIC-GRAPHITE ELECTRODES AND THE USE IN THE FERROCENE-MEDIATED AMPEROMETRIC MEASUREMENT OF GLUCOSE
A simple, fast and effective method for the immobilization of glucose oxidase onto a modified basal plane pyrolytic graphite electrode is described. To enhance the rate of electron exchange with the electrode, a ferrocene derivative was used as a mediator. The stability of the enzyme electrode was evaluated using direct current cyclic voltammetry.
