Outline of Final Research Achievements

In this study, free energy analysis based on molecular dynamics simulation was carried out for the binding/fusion process of two spherical micelles and the binding/fusion process of the spherical micelle to the lipid membrane surface. As a target system, SDS micelle, which is a representative spherical micelle, and a planar membrane patch of a lipid bilayer membrane composed of POPC as a model of a real cell membrane were used. Molecular level mechanism of fusion process due to thermal fluctuation was elucidated, and time constants required for micelle binding and fusion were evaluated.
