摘要:
摘要： A mesoscopic coarse-grain model for computationally efficient simulations of biomembranes is presented. It combines molecular dynamics simulations for the lipids, modeled as elastic chains of beads, with multiparticle collision dynamics for the solvent. Self-assembly of a membrane from a uniform mixture of lipids is observed. Simulations at different temperatures demonstrate that it reproduces the gel and liquid phases of lipid bilayers. Investigations of lipid diffusion in different phases reveals a crossover from subdiffusion to normal diffusion at long times. Macroscopic membrane properties, such as stretching and bending elastic moduli, are determined directly from the mesoscopic simulations. Velocity correlation functions for membrane flows are determined and analyzed. 其他題名： J Chem Phys 出版者： United States: AIP Publishing 出版日期： 2012-08-07 出處： The Journal of Chemical Physics, 2012-08, Vol.137 (5), p.055101 資源來源： AIP Journals (American Institute of Physics) 識別號： ISSN: 0021-9606 識別號： ISSN: 1089-7690 識別號： ISSN: 1520-9032 識別號： EISSN: 1089-7690 識別號： DOI: 10.1063/1.4736414 識別號： PMID: 22894383
