摘要

In this manuscript, well-defined copper(II) oxide nanowires (CuO NWs) structures were successfullysynthesized by simple, template- and surfactant-free two-step electrodeposition method. The obtainedCuO NWs were investigated using field emission scanning electron microscopy (FESEM) and X-rayphotoelectron spectroscopy (XPS). The electrochemical properties of the CuO NWs modified glassycarbon (CuO NWs/GC) electrode towards nonenzymatic detection of glucose (Glc) under alkalineconditions were studied by cyclic voltammetry (CV) and chronoamperometry. Excellentelectroreduction activity of CuO NWs towards Glc was observed. The CuO NWs/GC sensor wascharacterized by the wide linear range for Glc (0.0125-4.29 mM), high sensitivity (759.86 μA mM ?1cm ?2 ), short response time (4s) and the low limit of detection (LOD = 4.17 μM). Moreover, the sensorshowed good reproducibility, anti-interferant ability and long-term stability. Hence it suggests a potentialapplicability of CuO NWs/GC as a sensor for nonenzymatic detection and quantification of glucose.
