MS, Institute of Chemistry, Chinese Academy of Sciences, 1991.

BS, Beijing Normal University of China, 1986.

Research Interest: bioanalytical chemistry, physical chemistry, and nanoscience.

My research interests focus on the biological detection including carbohydrate, DNA, and protein using fluorescence spectra. We find that the fluorescence can be enhanced when the fluorophore is localized near the surface of metal particle and the enhancement is dependent on the features of particle such as size, shape, charge state, and aggregation, etc., as well as other factors like distance of fluorophore to metal surface and wavelength of fluorophore, etc. We prepare the nano-scale metal materials capped on the solid substrate or dispersed in solution by synthesis, vapor deposition, electrochemistry, lithography, and LB, etc, which are used to study the surface enhanced fluorescence (SEF). The SEF technique is used to study the biological detection.

Hobby: reading book and playing basketball.
