| 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.
