| Outline of Final Research Achievements |
Noble-metal (gold (Au), silver (Ag) and platinum (Pt)) nanoclusters consisting of several atoms have been applied for advanced biological application in sensing, cellular imaging, and biomedicine owing to their excellent physicochemical properties and biocompatibility, such as smaller size, less cytotoxicity, tunable fluorescence emission and high photostability. In this study, we have developed the biocompatible Pt nanoclusters as fluorescence and electron microscopic imaging probes, and have applied them to in vitro and in vivo imaging. Since the Pt nanoclusters are less cytotoxic as well as smaller than other nanoparticles such as quantum dots and carbon nanotubes, the fluorescent Pt nanoclusters promises to be a useful fluorescent probes for bio-imaging and long-term in vivo imaging.
