Outline of Final Research Achievements |
In this research project, we established the principle for controlling Raman signal based on the resonance Raman effect accompanied by changes in molecular absorption, and developed several functional Raman probes based on the principle. Specifically, we developed not only Raman probes whose Raman signals are activated upon reaction with enzymes such as aminopeptidases and glycosidases, but also Raman probes whose Raman signals are activated or switched in response to light irradiation. Furthermore, we applied the developed Raman probes to live cells and tissues to demonstrate the utility of these probes.

Academic Significance and Societal Importance of the Research Achievements |
本研究で確立した機能性ラマンプローブの分子設計をさらに拡張することで、生きた生物試料中における生体分子の機能や構造を従来法を凌駕する性能で可視化・検出するラマンイメージング技法が確立できると期待される。従って、生体解析ツールとしてのラマンイメージングの性能を飛躍的に拡張するとともに、医学・薬学・生物学に画期的な進展をもたらすと考えられ、それ故に学術的・社会的意義が極めて大きい成果といえる。
