Abstract

EN This work presents development of an innovative CuO/nitrogen-doped carbon composite (CuO􀀀 C) that may be effectively applied for the modification of a glassy carbon electrode (GCE) and creation of a nonenzymatic sensor for glucose detection. The structure of the CuO-C nanostructured material was analyzed by scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray diffraction, and atomic absorption spectroscopy. The prepared electroactive material, based on CuO including carbon structures derived from chitosan, showed excellent performance in terms of electrocatalytic oxidation of glucose. Under optimal conditions, the modified electrode displays high sensitivity, a low detection limit (1.95μM) and short response time (4s).
