The CuO nanoplatelets were synthesized by hydrothermal method. The structure and morphology of the CuO nanoplatelets were characterized by TEM and XRD. A new nonenzymatic glucose sensor was constructed by immobilizing the CuO nanoplatelets on glassy carbon electrode with Nafion. The electrochemical performance of the CuO/Nafion/GCE for the detection of glucose was investigated by cyclic voltammetry and current-time curve. The experiment results showed that the linear dependence of the sensor was 0.01 to 0.3 mmol·L-1 for glucose with a sensitivity of 1783.58 μA·mmol-1·L·cm-2, and the detection limit of the sensor was 0.80 μmol·L-1 (S/N = 3). Also, the sensor displayed fast response and long-term stability to glucose, and interferences of ascorbic acid, dopamine, and uric acid were effectively avoided.
