五、研究方向： We are interested in the development of Raman Techniques (Dispersive Raman, FT-Raman, and Surface Enhanced Raman Scattering) to explore bioactive molecules of natural products and to characterize molecular structure of biomacromolecules. Raman spectroscopy is well known for its capability of providing rich molecular information. However, the application of Raman technique in studying natural pigments is usually hampered by the strong fluorescence signals arising from the intrinsic chromophores/fluorphors of natural pigments in plant. To overcome this problem, the development of Fourier transform Raman spectroscopy (FT-Raman) excited at near-infrared wavelength has demonstrated tremendous breakthrough. Although FT-Raman has made much progress in relaxing fluorescence interference and also has exhibited much spectroscopic superiority such as simple, direct, and free from photo bleaching due to the advantages of near infrared excitation, and the high throughput and multiplex characteristics of Michelson interferometer, it remains suffering from the shortcoming of low sensitivity, particularly for the solutions at low concentration. Therefore, to develop a high sensitive Raman technique to characterize nature pigments remains an important issue. With the aid of nano technique, we are developing surface-enhanced Raman scattering (SERS) to be an excellent ultra sensitive tool in probing trace molecules of natural pigments such as catechins and anthocyanins, of which Raman signals are usually overwhelmed by the strong fluorescence arising from their intrinsic chromophores/fluorphors. Research projects for this part include: (1) Separation, purification, and identification of bioactive compounds from Yam (2) Raman spectroscopic study of natural pigments such as catechin and anthocyanin (3) Developing ultrasensitive Raman detection system. The second part of our research goal is to characterize protein structure by Raman spectroscopy. We have worked on eye lenses and lens proteins for years. Understanding the factors of various protein perturbations and to prevent lens from oxidative insults will lessen cataract formation that is a result of protein aggregates and remains an unsolved problem in human being. There remains no efficient method to diagnose cataract formation at its early stage, as a noninvasive tool Raman spectroscopy sheds some light on probing cataract at its early stage. The ongoing research includes purification of lens crystallins from eye lenses and characterization of their structures by Raman spectroscopy.
