The technique consists of NH₃ plasma treatment of hydrogenated diamond substrate to generate surface terminal amino groups. The aminated diamond surface was further investigated for its ability to bind gold nanoparticles. Homogeneous and well-distributed gold nanoparticles were obtained by simple exposure of the amine-terminated surface to an aqueous solution of gold colloid. The resulting surfaces were characterized using X-ray spectroscopy (XPS), scanning electron microscopy (SEM) and cyclic voltammetry (CV). The presence of gold nanoparticles led to more reversible electron transfer process on the modified electrode.Show less >
