RESEARCH INTERESTS:

Biophysical Chemistry and Technology Development

Our objective is the advancement of bio-analytical sciences and biophysics in a systematic and complementary manner. Both fundamental biophysical knowledge and technical innovations are essential for resolving critical problems, such as high-throughput diagnoses, accurate quantifications and molecular function examinations. We have studied the physics and chemistries involved in the development of key analytical technologies, and integrated them for express clinical diagnoses. The fundamental study of ionization mechanism of biomolecules is one of our focuses, which enables us to design an effective strategy to improve the detection of carbohydrates. The technologies developed in this laboratory include:

  • Synchronized Dual-Polarity Mass Spectrometry
  • Synchronized Dual-Polarity Imaging Mass Spectrometry
  • Soft Protonation Method for Carbohydrates
  • Ultra-Sensitive Surface Ionization Method for Carbohydrates
  • Structural and Energetic Simulation of Oligosaccharides
  • Nanoparticles for Selective Purification of Phosphoproteins
