Abstract:

A non-enzymatic glucose sensor using novel porous foamy CuO micro-nanofibers was fabricated through electrospinning and subsequent calcination. Scanning electron microscopy(SEM), Fourier transform infrared spectrum(FTIR) and X-ray differaction(XRD) techniques were used for the morphology and structural characterization of CuO nanostructures. CuO micro-nanofibers are highly dense, uniform, and exhibited good crystalline array structure. Most of all, the product presents a special rough foamy morphology with many pores, which help to enlarge the specific surface area thereby enhancing the activity of electrooxidation of glucose. The prepared CuO micro-nanofibers were subsequently used to modify a glassy carbon electrode and then detailed investigated for direct electrocatalytic oxidation of glucose through cyclic voltammetry and chronoamperometry. The results manifest that the modified electrode has a good sensitivity of 6.17 μA·L·mmol-1·cm-2 and a low detection limit of 65.3 μmol/L. Moreover, it exhibits a good antiinterference to ascorbic acid(AA), uric acid(UA) and ethanol as well. The improved performances were ascribed to the high surface-to-volume ratio and the special morphology. Therefore, it concluded that the porous foamy CuO micro-nanofibers can be a promising non-enzyme glucose sensor.
