Metallic nanoparticles or nanocrystals are being developed for a variety of applications including catalysis, drug delivery and contrast agents for high-resolution imaging. We have demonstrated the general utility of PEGylated dithiolane ligands for direct synthesis of high quality water-soluble Au, Ag, Pt, Pd, Cu and alloyed/bi-metalic nanoparticles. The PEGylated ligands with different terminal groups can be used to allow for the bio-functionalization of Quantum dots, magnetic nanoparticles, and many other types of core/ shell nanoparticles. Additionally these ligands are suitable for use with a variety of different reducing methods that control the shape and size of nanoparticles. The prepared nanoparticles exhibit remarkable stability in various chemical environments and the controlled functionalization of the surface expands the potential areas of application.
