Summary: Potentiostatic anodization was used to synthesize nanostructured copper oxide/copper (CuxO/Cu, x=1,2) electrodes for sensitive non-enzymatic glucose detection. The CuO/Cu electrode exhibited a high sensitivity of 2954.38 mu A mM(-1) cm(-2) to glucose and a linear range of 0.1 mM to 1.3 mM at a catalytic potential of 0.55 V. The electrode showed a fast response time of less than 3 s with the addition of 0.1 mM glucose. The nanostructure of the electrode, achieved through anodization in 1M KOH solution at -100 mV, contributed to the efficient glucose catalytic oxidation process and could be controlled by adjusting the potential and electrolyte concentration during anodization.
