Abstract: This work presents a viable method for synthesis carbon nanoparticles decoration zinc oxide nanostructured films and synthesizing pure ZnO films for glucose sensors. Anodization was used to grow zinc oxide nanoparticles on zinc foil with an average particle size of 22.77 nm, and hydrothermal synthesis was used to create carbon nanoparticles. The ultrasonication method was used to decorate ZnO film nanocomposites with carbon nanoparticles. several tests were carried out, including observations of the microstructure, analyses of the crystallinity, and investigations of the electrochemical properties. X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDX), field-emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), and photoluminescence (PL) measurements were used to determine the nanostructures. The electrochemical analysis of the CNPs/ZnO nanostructures greatly improved the sensitivity to glucose compared with pure zinc oxide nanostructures, with a sensitivity of (1975 µA.mM-1.cm-2), the CNP/ZnO nanostructures improved glucose sensing. The low detection limit is (0.3 mM), and the linear range is 0.3 mM to 0.7 mM.
