    Abstract: A novel Ni (Nickel)/CS(chitosan)/CNT(carbon nanotube) network nanocomposite was constructed on graphite electrode for glucose detection . Firstly, multi-walled carbon nanotubes were purified and characterized by Fourier transform infrared (FT-IR) spectroscopy, scanning electron microscopy (SEM). The modified electrode with the Ni/CS/CNTs showed excellent electrocatalytical response to the oxidation, which was studied by cyclic voltammetry (CV). The synthesized biosensor exhibited rapid response, low detection limit, broad linear range, good reproducibility and stability.

    Keywords: Glucose, Nickel nanoparticles, Chitosan, multi-walled carbon nanotube, Oxidation.
