Research Abstract |
In this project, we have addressed a construction of a minimum theoretical model to describe dynamics of artificial multi-component lipid membranes and vesicles. By using the model, we performed numerical simulations to reveal the physical origin of various phenomena seen in biomembranes from physical points of view. We investigated various membrane systems (for example, dynamics of a pore-rim-rolled vesicle, effect of hydrodynamic flow inside and outside of vesicle and effect of intra-membrane hydrodynamics on their dynamics, and effect of asymmetric distribution of stress between two leaflets in lipid bilayer) , where intra-membrane degree of freedom play essential role.
