Spherulitic copper-copper oxide nanostructure-based highly sensitive nonenzymatic glucose sensor.

ABSTRACT: In this work, three different spherulitic nanostructures Cu-CuOA, Cu-CuOB, and Cu-CuOC were synthesized in water-in-oil microemulsions by varying the surfactant concentration (30 mM, 40 mM, and 50 mM, respectively). The structural and morphological characteristics of the Cu-CuO nanostructures were investigated by ultraviolet-visible (UV-vis) spectroscopy, X-ray diffraction, scanning electron microscopy, and high-resolution transmission electron microscopy techniques. The synthesized nanostructures were deposited on multiwalled carbon nanotube (MWCNT)-modified indium tin oxide (ITO) electrodes to fabricate a nonenzymatic highly sensitive amperometric glucose sensor. The performance of the ITO/MWCNT/Cu-CuO electrodes in the glucose assay was examined by cyclic voltammetry and chronoamperomet
