| Outline of Final Research Achievements |
This study aims to develop a highly sensitive measurement method for single nanoparticles in liquid. Scattered light from a particle by a focused laser irradiation can be detected by lock-in heterodyne interferometric technique. Finally, we succeed in the detection of the scattered light signal from a 20nm-nanoparticle flowing in a microfluidic device.

| Academic Significance and Societal Importance of the Research Achievements |
本研究で開発したナノ粒子計測技術は，これまでは液中に多数の粒子が必要であったナノ粒子計測のキャラクタリゼーションをより希薄粒子系に対して実現できるようにするものであり，新規ナノ物質の定量評価を大きく推進することが期待される．
