Jinsuo Zhang, Yi Jiang, Steen Rasmussen and Hans Ziock, "Lipid aggregation as a function of aggregation number", Preprint: LA-UR-05-5480, 2005


Dissipative particle dynamics simulation is used to study lipid aggregation phases as a function of the lipid aggregation number. We observe sphere-like, rod-like, disk-like micelles, and vesicles as well as bilayers with or without pores. Properties of each phase are discussed. The lipid tail particles are very disorder in the aggregation structure and head particles aggregate into clusters on the surface of the structure under the present simulation conditions. The radius of the sphere-like micelles and vesicles can be correlated by the aggregation number. We find the vesicle thickness does not change with the lipid number increasing, while the ratio between the lipid number at the inertial mono-layer to that at the outer mono-layer increases with the lipid aggregation number increasing.
