Abstract

Silver nanostructures were successfully synthesized through a simple and ‘green’ route using starch as a capping agent. High resolution electron microscopy (HREM), X-ray diffraction (XRD), UV–Vis absorption suggested that Ag nanocrystals, having a size lower than 10 nm, were obtained, in addition a self-assembly into ribbon-like structures was been also observed. The silver nanostructures were electrodeposited onto suitable substrates with gold interdigital electrodes realizing amperometric sensors that showed a high sensitivity to hydrogen peroxide.
