Outline of Final Research Achievements

In this study, we suggest a nano particle sizing method with in-situ measurement of the solvent viscosity. It is considered that the average size of the nano particle is accurately estimated based on the simultaneous measurement for both the particle size and the solvent viscosity. The fluorescent nano probe is attached on the particle before the particle sizing. Then the translational diffusion time of the fluorescent nano probe is measured by using the originally constructed equipment for photon correlation measurement of the fluorescent signal from the fluorescent nano probe. It is considered that both the rotational diffusion time and the translational diffusion time are required to determine the viscosity of the solvent. It is possible to determine the translational diffusion time of the fluorescent nano probe by using the originally constructed equipment to measure the viscosity of the solvent.

Academic Significance and Societal Importance of the Research Achievements

液層中のナノ粒子の粒度分布評価は,溶媒中のナノ粒子の球相当径を測定する方法が一般的である.しかしながら,その計測には,溶媒の粘度の測定が必要であり,事前にナノ粒子の分散する溶媒の粘度を正確に推定することは困難である.本研究課題は,ナノ粒子の分散する溶媒の粘度およびナノ粒子の粒径の測定が同時に行うことを提案するものであり,提案手法により,拡散法で評価されるナノ粒子の粒度分布測定の不確かさ評価が可能になると考えられ,その学術的意義は大きい.また,ナノ粒子の平均粒径の保証が行えるようになれば,その工業的価値は高く,社会的な意義も大きいと考えられる.
