Outline of Final Research Achievements

We prepared various calixarene-based micelles as a model system of Janus micelles. Their aggregation behavior was characterized using small angle scattering techniques including small angle X-ray scattering. We elucidated the correlation between structural parameters, such as the ionic strength of the hydrophilic part and the volume of the hydrophobic part, and the aggregation behavior of Platonic micelles, which would be helpful for designing Janus micelles in the future.

Academic Significance and Societal Importance of the Research Achievements

プラトニックミセルは会合数に分布がなく真に単分散であるため、会合数の決まったナノ粒子の構造制御法として重要な技術となり、広範に応用され得る。例えば、ドラッグデリバリーシステムにおいて、ナノキャリアの大きさや形状の精密制御ができていないことが重大な問題となっているが、プラトニックミセルはその問題を解決し得る。また、本研究成果により明らかにしたプラトニックミセルの会合挙動は、新規プラトニックミセルの調製において重要な知見となる。
