Coarse-grained (CG) molecular models are now widely used to understand the structure and functionality of macromolecular self-assembling systems. In the last few years, significant efforts have been devoted to construct quantitative CG models based on data from molecular dynamics (MD) simulations with more detailed all-atom (AA) intermolecular force fields as well as experimental thermodynamic data. We review some of the recent progress pertaining to the MD simulation of self-assembling macromolecular systems, using as illustrations the application of CG models to probe surfactant and lipid self-assembly including liposome and dendrimersome formation as well as the interaction of biomembranes with nanoparticles.
粗粒化(CG)分子模型现在被广泛用于理解大分子自组装系统的结构和功能。在过去的几年中,人们已经投入了大量的努力,根据来自分子动力学(MD)模拟的更详细的全原子(AA)分子间力场以及实验热力学数据,构建定量 CG 模型。我们回顾了一些关于自组装大分子系统的 MD 模拟的最新进展,用 CG 模型来探测表面活性剂和脂质自组装的应用,包括脂质体和树枝状大分子的形成以及生物膜与纳米颗粒的相互作用作为例子。
