Cu nanoclusters were electrochemically deposited on the film of a Nafion-solubilized multi-wall carbon nanotubes (CNTs) modified glassy carbon electrode (CNTs-GCE), which fabricated a Cu-CNTs composite sensor (Cu-CNTs-GCE) to detect glucose with non-enzyme. The linear range is 7.0×10^-7 to 3.5×10^-3 mol/L with a high sensitivity of 17.76 μA/(mmol L), with a low detection limit 2.1×10^-7 mol/L, fast response time (within 5 s), good reproducibility and stability.
