| Abstract: | The principle, technique, the features and the most recent development of Tip-Enhanced Raman Spectroscopy (TERS) were introduced from the aspects of how to improve the detection sensitivity and the spatial resolution of Raman spectroscopy. The high sensitivity of TERS was demonstrated using the molecular adsorption on single crystal surfaces and the high spatial resolution was demonstrated by imaging single-wall carbon nanotubes. The present status of the theoretical aspect of TERS was also introduced. Finally the perspective of TERS was given. |
