| Outline of Final Research Achievements |
Ti-enhanced Raman spectroscopy (TERS) is a powerful technique that enables optically analyzing nanomaterials with a spatial resolution down to nanometer scale. In this study, I investigated the possibility of analyzing molecular dynamics using TERS. Based on AFM apparatus, I have build a molecular tracking system, with which it is capable to position a probe onto a spatially moving molecule, such as motor protein molecule. I have also designed and fabricate a metallic probe which provides high TERS enhancement by optimizing the resonant frequency of the plasmonic antenna at the tip. The results obtained in this study suggests the possibility of measuring molecular dynamics in nanoscale using TERS.
