CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishSilver 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.
