Abstract

One of the challenges in the field of enzymatic biofuel cells is to significantly improve their current limited lifetime. In the present work, we report the covalent immobilization of enzyme layers on glassy carbon electrodes, functionalized via electrochemical reduction of in situ generated aryldiazonium salts bearing carboxylic acid groups. We present the performance and the stability over time of the modified electrodes. For glucose oxidase - modified electrodes, stable catalytic activity is observed for a minimum of 6 weeks.
