In this manuscript, an attempt has been made to synthesize well-crystallized flower-shaped copper oxide hierarchical structures by simple solution process for fabrication of nonenzymatic glucose sensor under alkaline conditions. Scanning and Transmission electron micrographs clearly illustrate that CuO structures are flower-like shape while X-ray diffraction (XRD) and Fourier Transform Infrared (FT-IR) analyses indicate the formation of pure CuO monoclinic phase. Modified electrode with CuO microflowers shows a wide linear response towards glucose in the concentration range of 10-120 mu M with a detection limit of 6.48 mu M (S/N = 3). Such results have revealed that CuO microflowers show excellent electrocatalytic activity and efficient electron transport property; hence it may be a promising candidate for the nonenzymatic glucose sensor applications.
