| Research Abstract |
The following results were obtained.
1)Single molecule detection using SERS : a)Critical importance of the junction was proved using correlation between SERS and elastic scattering spectra from the same Ag nanoparticles, 2)adenine which has no electronic absorption in visible wavelength provides enormous enhancement similar to dye, 3)emission spectra originated from inelastic scattering of surface electron by adsorbed species was found for the first time.
2)ATR-SNOM-Raman spectroscopy : a)interference or multiple scattering of LSP field do no essentially affect the near-field Raman imaging.
3)FT-IR based ATR near-field spectrometer was built to demonstrate tip-enhanced IR absorption.
4)Slab optical waveguide spectroscopy : ITO based waveguide was fabricated and applied to elucidate potential dependence of biomolecules with significantly high sensitivity.
