| Research Abstract |
Scanning probe electron-enhanced Raman scattering microscope has been developed. Various methods for the generation of electrons from a metal tip by laser excitation were investigated experimentally. We found that the optimal method was the introduction of the tip to the near-field area excited by total internal reflection of laser beam. This is because it is appropriate for the illumination under spatially restricted sample chamber and is easy for the application to various samples in water. In addition, the combination of the FM modewith the optimized optical arrangement allowed us high-resolution measurements at single molecular resolution level. We have applied the instrument developed here to the measurements on carbon materials, lipid or protein self-assemblies for the test of the Raman enhancement factor and of the ability to measure the mechanical responses
