Outline of Final Research Achievements

Time-resolved molecule probe microscopy that was combined scanning probe microscopy and mass spectroscopy was developed. Capillary for electrospray ionization was used for the probe like a cantilever of atomic force microscopy. Projection method was used for the measurement of capillary displacement. The relationship between capillary motion and the size of solvent bridge were elucidated. Furthermore, the effect of the solvent bridge on the sensitivity of mass signal is also investigated. For a demonstration of this method, we focused on a chemical reaction induced by plasmon excitation of Au nanoparticles. The lifetime of excited charges was measured.

Academic Significance and Societal Importance of the Research Achievements

時間分解分子プローブ顕微鏡は、時間を追って変化する表面上分子の分布状態を映画のコマ送りのように追跡する方法である。本手法が完成すれば、触媒化学、バイオチップ、有機太陽電池、レジスト開発など、非定常的な電荷発生とそれに続く化学反応の時間変化とナノスケールにおける分布状態を知ることができる。
