Abstract
Glucose detection is important in biological, environmental, and clinical analyses. In this study, Au modified CuO
nanosheets (Au/CuO NSs) el ectrode was prepared and applied to construct nonenzymatic glucose sensor. The CuO NSs
were characterized by scanning electron microscopy (SEM) and X ray diffraction (XRD). Electrocatalytic oxidation of the
Au/CuO NSs electrode towards glucose was studied by cyclic voltammetry (CV) and chronoamperometry. For the
amperometric glucose detection, the low detection limit of 1 µM (S/N=3) with linear range from 1 µM to 17 00 µM can be
obtained using the Au/ CuO NSs electrode. Under the applied potential of 0. 6 V, t he Au/CuO NSs electrode exhibited a
high sensitivity of 3370.1 µA mM 1 cm 2 ..
