Overview of Research and Education

Research Contents: Biological system is the typical example of the general concept of supramolecule, where the numerous functions are originated from the complex interactions among the biologically active molecules, cells, tissues and organs. Using non-invasive techniques, such as optical method, our research is targeting the functions and structures of the system from the single molecule to cell and cells such as brain, for understanding supramolecular system. Furthermore, various new optical techniques are developing to analyze these systems and to establish the new methodology in biomedical field.

  1. Study of the higher cell function by optical imaging technique.
  2. Investigation of tissue spectroscopy using time-resolved technique and fluctuation spectroscopic techniques such as lifetime measurement, fluorescence correlation spectroscopy and single molecule detection.
  3. Spectroscopic analysis of formation and toxicity in neurodegenerative disorder-linked protein aggregation in the cell.
