title: Metal nanoparticles: in-situ stabilization, characterization and reactivities.
abstract: We report here, the technique for preparation, characterization and reactivities of different metals (Cu, Ni, Au, Ru, Pt etc.) nanoparticles. The stabilized metal nanoparticles are, in general, very active as catalysts, e.g., hydrogenation (with H2/transfer hydrogenation) of nitro to amino group, ketone to alcohol and also oxidation of alcohol to Ketone/aldehyde. Metal nanoparticles, due to their smaller size than bacteria, tissues etc. and high reactivities, must have high impact on safety, health and environment and therefore, a systematic study of the effect of metal nanoparticles in these aspects need be carried out.
