摘要

A novel amperometric glucose biosensor based on hybrid nanostructure of ZnO nanorods and Aunanoparticles was investigated, and the morphologies of various self-assembly time of AuNP by self- assembly method on the ZnONR were discussed. The ZnO nanorods (ZnONR) provide a 1-D electrontransmission path and the Au nanoparticle (AuNP) was used to enhance the sensitivity. Furthermore,the ZnONR arrays were fabricated by chemical bath deposition which was an aqueous depositiontechnique on ITO electrode. For the bioelectrochemical properties of glucose sensing, the linear rangeof the ZnO-Au hybrid nanostructure is 1.38~22.22 mM with sensitivity of 1.44 A/mM and the limitof detection (LOD) is 3.51M.
