An ultrasensitive mini-sensor has been developed for nonenzymatic and noninvasive determination of trace glucose in saliva. The miniature detector exhibits ultra-high sensitivity and resolution at very low glucose concentration owing to the excellent electrocatalytic activity and electron transfer rate of the prepared 3D ordered CuO nanoflake array in-situ grown on a copper foil. The structure and morphology of the cupric oxide nanoarray were characterized by X-ray powder diffraction and scanning electron microscopy. The electrocatalysis of the CuO nanoarray modified electrode to glucose was demonstrated by cyclic voltammetry and chronoamperometry. The modified electrode presents a high sensitivity of 4954 μA mM |
