Straightforward green synthesis of 'naked' aqueous silver nanoparticles

摘要

Water-soluble, exceptionally stable, "naked" silver nanoparticles were obtained in a single step by simple decomposition of a commercial silver complex at room temperature without the need of external reducing agents and conventional stabilizing ligands.rnIn the fascinating realm of nanostructured materials, noble metal nanoparticles (NPs) have been receiving a great deal of attention. The wealth of their unique properties makes NPs ideally suited for widespread applications in different fields ranging from diagnostic imaging and drug delivery to optoelectronics and catalysis. This scenario has stimulated a surge of interest in the developing of synthetic protocols for NPs. Syntheses have been performed in a variety of conditions by reductive chemical methods, sonochemical and photochemical techniques using a multiplicity of chemical and biochemical stabilizing ligands to avoid aggregation.
