Since their discovery in 1991, carbon nanotubes (CNTs) have attracted a tremendous amount of attention due to their extraordinary physical, chemical, and mechanical properties. The large surface area of the CNTs offers abundance reactive sites to generate Faradic currents, and the reactions on CNT-modified biosensor (typically glucose sensors) electrodes belong to the surface-controlled process and have shown direct electron transfer property. We fabricated non-enzymatic amperometric glucose biosensors using nanoparticles (e.g., Pt, Ru, Pd, Cu2S, avg. size = 8 nm)-CNT hybrid nanostructures, synthesized directly by the solvothermal method. In particular, the Cu2S nanoparticles decomposed catalytically the glucose into H2O2, and enhance greatly the performance of glucose sensors which is comparable to the enzymatic sensors. The double-walled CNTs respond more sensitively than the single-walled or multi-walled CNTs.
