Monte Carlo simulation study on bilayer vesicle shape

Abstract EN

Monte Carlo simulation method with new curvature Hami.ltonian is used to simulate the liposome vesicle shapes.

In the absence of spontaneous curvature, the liposome vesicle shows the oblate-liked shape.

The bending energy increases with the decrease of the reduced volume.

It is shown that oblate-shaped vesicles have the least bending energies.

Where as Sekimura 's biconcaved oval shapes are only in the local minimum state.

To explain the biconcaved vesicle shape, the spontaneous i curvature ought to be taken into consideration.

Moreover, the Monte Carlo method used in this work shows the full promise for the study of membrane shapes, having more complicated geometric structures
