We have focused on vanadium oxide (VOx) as an electrode material for pH sensors, which are a fundamental part of biosensors, and have reported that high sensitivity exceeding the Nernstian limit can be obtained. On the other hand, there have been few reports on the use of VOx electrodes for biosensors. Therefore, we developed a prototype EGFET-type glucose sensor using an extended gate (EG) electrode with GOD immobilized on a VOx thin film. In this presentation, we report that a highly sensitive glucose sensor with a high response to low concentrations of glucose has been fabricated.
