Abstract

Water soluble metallic nanoparticles are being developed for a variety of roles ranging from catalysis to drug delivery and as potential contrast agents. We demonstrate direct synthesis of high-quality water-soluble Au, Ag, Pt, Pd, Cu and alloyed AuPt nanoparticles as well as ligand-exchange of FePt, cubic Pt and Au/Pt core/shell nanoparticles using bidentate dithiolane PEG as a universal ligand. Simple chemistry can greatly expand the applications of metal nanoparticles.
