Outline of Final Research Achievements

Super resolution Raman microscopes have been developed by combining Raman spectroscopy, which provides valuable information concerning molecular structure and interaction, with localized plasmon around the surface of Au and Ag, which enhances Raman scattering to a larger degree at the near field, to realize a high spatial resolution beyond diffraction limit and a high sensitivity toward single molecule measurements. A confocal Raman microscope with a spinning disk confocal laser scanner has also been developed, which realize a higher scanning rate than a piezo stage and a galvano mirror. Optical images based on Raman scattering can be directly observed with cooled CCD camera by selecting appropriate Raman bands with band pass filters.
