摘要
Novel copper (Cu) film composed of pillar-like structure was synthesized on indium-doped tin oxide (ITO) substrate by electrodeposition in acetate bath with proline as additive for the first time and used to construct nonenzymatic glucose sensor. When applied to detect glucose, such prepared electrode showed low operating potential (0.4 V), high sensitivity (699.4499 mu A mM(-1) cm(-2)), and fast response time (<3 s) compared with other Cu-based electrodes. In addition, the prepared electrode also offered good anti-interference ability to ascorbic acid, uric acid and acetaminophen. Present study provides new insights into the control of Cu film morphology for sensor fabrication.
