本文报道了在渗透压差作用下发生相分离的三元囊泡的形状变形的实验研究。不同形状囊泡的相分离导致了独特的形变分支。在结构域粗化阶段，扁长囊泡、盘细胞囊泡和海星囊泡表现出向盘细胞的形状收敛，而管状囊泡则表现出珍珠状不稳定性。在后期阶段，取决于多余的区域，域开始朝向囊泡的内部或外部出芽。在薄膜弹性模型的基础上讨论了变形分支。
We report an experimental study on shape deformations of ternary vesicles undergoing phase separation under an osmotic pressure difference. The phase separation on various shape vesicles causes unique shape-deformation branches. In the domain coarsening stage, prolate, discocyte, and starfish vesicles show a shape convergence to discocytes, whereas a pearling instability is observed in tube vesicles. In late stages, the domains start to bud towards the inside or outside of the vesicle depending on the excess area. We discuss the deformation branches based on the membrane elasticity model.
