Self-assembly of amphiphiles into vesicles: a Brownian dynamics simulation.
We studied the vesicles of amphiphilic molecules using a Brownian dynamics simulation. An amphiphilic molecule is modeled as the rigid rod, and the hydrophobic interaction is mimicked by the local density potential of the hydrophobic particles. The amphiphilic molecules self-assemble into vesicles with bilayer structure. The vesicles are in fluid phase, and we calculated the lateral diffusion constant and the rate of the flip-flop motion of molecules in vesicles. The self-assembly kinetics into vesicles was also investigated.
