Outline of Final Research Achievements

The kinetics of physiologically active small gaseous molecules such as odor molecules and inhalational anesthetics are poorly understood because direct microscopy observation of these molecules is difficult. In this research project, we develop a new coherent Raman microscopy that enables us to measure the spatial distribution of gaseous molecules with high sensitivity, without using labelling. We establish a new analytical method that can monitor the transport, localization and metabolism of gaseous molecules in cells and tissues. The new method can be used to directly measure small molecules in a tissue at a few millimolar (=mmol/L) concentration.

Academic Significance and Societal Importance of the Research Achievements

本研究で新たに提案された時間的に非対称な光パルスを用いた分子振動検出法は、超高速光学分野において全く新しい時間領域の光学設計に基づいており、それ自体に学術的価値がある。しかしそれ以上に、この手法によって生体組織中で検出できる分子濃度の限界を打破できたことは学術的にも実用的にも大きな価値がある。この新しい顕微鏡の解析手法は気体分子に限らず、多くの小分子薬剤、組織モデルに適用できるため、その恩恵は本研究課題でターゲットとした生命科学分野だけでなく、食品、化粧品、製薬分野などバイオメディカル分野に広く波及することが期待される。
