The detection of glucose has important significance in the food industry and clinical medicine, especially in the diagnosis of diabetes. In recent years, electrochemical nonenzymatic glucose sensors have attracted intensive attention to detect the glucose level with great progress. Up to now, different enzymatic glucose sensors are commonly used in glucose detection. However, considering some intrinsic disadvantages of these sensors, such as high fabrication cost and poor stability, non-enzymatic glucose sensors have attracted increasing research interest [3,4]. Herein, the activity of iron oxide/copper oxide heterostructure for glucose sensing was studied in KOH electrolyte by different electrochemical methods. Experiments revealed that the Fe2O3/CuO shows high sensitivity of 317.9 mA cm-2 mM-1, a wide linear range (0-50 mM), along with high selectivity, and applicability for glucose detection in real samples.
