摘要：

We report here the direct electron transfer of GOD and a novel glucose biosensor based on carbon-decorated ZnO(C-ZnO) nanowire array electrode. The C-ZnO nanowire array provides a novel platform for fast direct electrochemistry of GOD, and its based biosensor shows very high sensitivity and low detection limit. Based on the direct electrochemistry of horseradish peroxidase (HRP), the H2O2 biosensing application is further demonstrated using this new C-ZnO array architecture. The high conductivity of carbon and good electron transfer capability of ZnO nanowires, along with their low cost and biocompatibility make the C-ZnO nanowire array a promising platform for direct electrochemistry of enzymes and mediator-free enzymatic biosensors.
