Phys. Rev. E 67, 060901(R) (2003) [3 pages]Molecular simulations of mesoscopic bilayer phases
Dissipative particle dynamics simulations are used to study the self-assembly of lipids into bilayers. With a simple mesoscopic lipid-water model, we observe the formation of the liquid crystalline phase Lα and gel phases in which the tails are interdigitated LβI or noninterdigitated Lβ. For double-tail lipids experiments show all three phases, while for single-tail lipids only Lβ and Lα are observed. We show that at sufficiently high head-head repulsion the LβI is stable for single-tail lipids. This suggests that it might be possible to induce an Lβ→LβI transition by adding chaotropic salts. © 2003 The American Physical Society URL:
