Modelling and Simulations of Multi-component Lipid Membranes and Open Membranes via Diffusive Interface Approaches

Xiaoqiang Wang, Qiang Du

摘要:

本文建立了不同脂质组成的多组分囊泡膜和自由边界膜的相场模型。这些模型被用来模拟弹性弯曲能量和线张力能量与指定的体积和表面积约束下的膜的变形。通过比较我们的数值模拟与最近的实验,它表明,相场模型可以捕捉到丰富的现象与膜的转变,因此它提供了很大的功能,在模拟和建模的多组分膜。

英文摘要:

In this paper, phase field models are developed for multi-component vesicle membranes with different lipid compositions and membranes with free boundary. These models are used to simulate the deformation of membranes under the elastic bending energy and the line tension energy with prescribed volume and surface area constraints. By comparing our numerical simulations with recent experiments, it is demonstrated that the phase field models can capture the rich phenomena associated with the membrane transformation, thus it offers great functionality in the simulation and modeling of multicomponent membranes.
