1. A method for fabricating a nonenzymatic glucose sensor, comprising the following steps of:
(a) providing a bottom substrate;
(b) preparing a graphene layer on the bottom substrate;
(c) depositing a plural amount of zinc oxide (ZnO) seed crystals on the graphene layer;
(d) growing the ZnO seed crystals into columnar ZnO nanorods with a hydrothermal method;
(e) depositing a thin film of cuprous oxide (Cu2O) on surface of the ZnO nanorods via an electrodeposition method; and
(f) grafting single-walled carbon nanotubes (SWCNTs) on a surface of the thin-film of Cu2O, by using Nafion fixative composited with SWCNTs.
