Abstract: A method for fabricating nonenzymatic glucose sensor, which comprises steps of: (a) providing a bottom substrate; (b) preparing a graphene layer on the bottom substrate; (c) depositing plural amount of zinc oxide (ZnO) seed crystals on the graphene layer; (d) growing the ZnO seed crystals into columnar nanorods with hydrothermal method; (e) coating a thin film of cuprous oxide (Cu2O) on the surface of the ZnO nanorods by electrochemistry-based electrodeposition; and (f) grafting single-walled carbon nanotubes (SWCNTs) on surface of the Cu2O thin film, by using Nafion fixative composited with SWCNTs. The structure of the above sensor, therefore, comprises a bottom substrate and other components orderly assembled on it, including, from inside to outside, a graphene layer, plural amount of ZnO nanorods, a Cu2O thin film, plural amount of SWCNTs, and the Nafion fixative. Accordingly, the sensor has advantages of low cost, rapid response, and easy for preservation.
