Novel techniques based on laser trapping - microspectroscopy on single micrometer-sized colloidal particles in solution as well as single aerosol water droplets in air have been developed. In particular, we have developed temperature- and moisture-controlled laser trapping of single aerosol water droplets in air. We also confirmed experimentally photoinduced aerosol droplet formation in air and its mechanistic aspects were elucidated. Furthermore, we succeeeded in determining the sizes of single aerosol droplets in a nanometer level based on whipering gallery mode resonances of Raman scattering light in single aerosol droplets. We also showed that the intraparticle diffusion of a cation dye in single cation-exchange resin microparticles was determined by the Donnan electric membrane potential generated at the resin/water interface, which was the first observation for single ion-exchange microparticles.

基于激光捕获的新技术——溶液中单个微米大小的胶体颗粒以及空气中单个气溶胶水滴的显微光谱学已经开发出来。特别是，我们开发了温度和湿度控制的激光捕获空气中的单个气溶胶水滴。我们还通过实验证实了空气中光诱导气溶胶液滴的形成，并阐明了其机理。此外，我们基于单个气溶胶液滴中拉曼散射光的回音廊模式共振，成功地确定了纳米级单个气溶胶液滴的尺寸。我们还表明，阳离子染料在单个阳离子交换树脂微粒中的颗粒内扩散是由树脂/水界面处产生的唐南电膜电位决定的，这是对单个离子交换树脂微粒的首次观察。
