| Outline of Final Research Achievements |
In order to measure nanoparticles in water, heterogeneous growth of nanoparticles in KCl supersaturated solution was applied so as to enable the optical detection of grown particles. The present work revealed that 0.3 microm particles grow to particles larger than 0.5 micron at a supersaturation bewteen 1.005-1.010 without homogeneous nucleation. Although the present work suggested the possibility of detenction of nanoparticles with heterogeneous nucleation, further study is required to increase supersaturation ratio of salt solution without homogeneous nucleation.
