Abstract
Nickelocene is investigated as an electrochemical mediator in glucose oxidase amperometric electrodes. The formal redox potential of nicKelocene /nickelocenium obtained in adsorbed state on electrochemically pre-treated (activated) pyrolytic graphite electrode,is -0.1 V (vs. Ag/AgCl). Adsorbed nickelocene mediates the charge transfer between the electrode and glucose oxidase. The steady-state amperometric response of nickelocene mediated enzyme electrode is investigated as a function of the glucose concentration, applied potential and pH of electrolyte.
