Computer Simulation of Vesicle Fusion

摘要

A dissipative particle dynamics simulation method is used to get insight into molecular-level details of vesicle fusion in this study. For simplicity, the simulation system contains water and amphiphiles. The fusion mechanism is investigated in detail. It is found that the whole fusion process is in well agreement with the "stalk-pore" hypothesis. The dynamics of vesicle fusion is analyzed by monitoring the time evolutions of morphologies.
