| Sumario: | In this chapter, a nanosensor based on Cu-doped ZnO nanoparticles (CZO NPs) for non-enzymatic glucose sensing has been elaborated. An electrochemical method, cyclic voltammetry (CV), has been developed for the detection of glucose. CZO was synthesized by the sol-gel technique, and its structural and morphological features were investigated by TEM, FTIR, and XRD. The elaborated ITO/CZO electrode was studied CV and electrochemical impedance spectroscopy (EIS). Indeed, the detection of glucose exhibited a large linear range in the range of 10−9 M–10−4 M and a low detection limit of 8 × 10−10 M. The response nanosensor was evaluated for various interfering species. Finally, the developed nanosensor was successfully tested on glucose determination in human serum samples. |
