Research Field

The perspective of PERS group is to build, develop, modify and employ the spectroscopic theories and methods to answer questions in surface science.

Main research contents involve: (1) To design, develop and modify spectroscopic methods and instruments for learning the interaction between molecules, e.g., SPR-SERS co-detection and SERS optical fiber sensors for chemical and bio analysis and detection. (2) Exploring new spectroscopic and experimental methods for self-assembly systems. We developed many high-sensitive techniques, e.g. waveguide-enhanced SERS, directional SERS, plasmonic nanoantennas,  to investigate the physical chemical subjects about surface and interface and the mechanism of SERS on metals.  (3) Utilizing spectroscopic techniques and theories to study on the relations of structure, function, and molecular interaction in the self-assembly systems and metal colloids. We applied many metal nanoparticle-assembled film for SERS, SEF, textile staining, and antibacteria etc.
