| Research Abstract |
Various materials to increase the efficiency of laser desorption of nonvolatile biomolecules were explored. Gold nano particle and carbon black were concluded as the best materials. The development enables us to determine structures of catecholamines and related molecules systematically by their UV and IR spectra. Picosecond time-resolved IR spectroscopy was applied to ionization triggered water migration dynamics in acetanilide-water system. This revealed details of the dynamics of single water molecule from the molecular point of view for the first time. Vibrational sum-frequency generation and optical microscope were combined to develop an IR super-resolution microscopy. 14 times higher spatial resolution than the IR diffraction limit was achieved and internal structures of cells were successfully visualized.
