Ligand-protected metal (Au, Au, Cu) nanoclusters have been investigated extensively because of their unique physicochemical properties and applications in fields such as optics, catalysis, chemical sensing, and magnetism. A number of ligand-protected Au or Ag nanoclusters with phosphine or thiorate ligands have been synthesized and studied in detail. The properties of ligand-protected metal nanoclusters can be \u201ctuned\u201d by the choice of the protecting ligands as well as the size of the clusters (i.e., the number of Au atoms in the cluster core). The electronic and optical properties of metal nanoclusters depend strongly on the cluster core, while the surface ligand species affect the surface chemistry, for example, solubility and solution-phase properties. In some cases, the surface ligand also influences the fluorescence of metal nanoclusters. Our groups focus on synthesis of water-soluble metal (Au, Ag, Cu) nanoclusters and their applications such as photoluminescence, sensing, PDT Application, Antibiotic properties for Biomedical Applications, and Photo\/Synthetic Catalysis.
