Understanding and controlling vesicle shapes is fundamental challenge in biophysics and materials design. In this paper, we employ the Monte Carlo method to investigate the shape of soft vesicle induced by semiflexible polymer outside in two dimensions. The effect of bending stiffness κ of polymer and the strength εVP of attractive interaction between vesicle and polymer on the shape of vesicle is discussed in detail in the present paper. It is found that the shape of vesicle is influenced by κ and εVP. Typical shape of vesicles is observed, such as circular, cigar-like, double vesicle, and racquet-like. To engineer vesicle shape transformations is helpful for exploiting the richness of vesicle geometries for desired applications.
理解和控制囊泡形状是生物物理学和材料设计中的一项基本挑战。在本文中，我们采用蒙特卡罗方法来研究二维空间中半柔性聚合物在外部诱导的软囊泡的形状。本文详细讨论了聚合物的弯曲刚度κ以及囊泡与聚合物之间吸引相互作用的强度εVP对囊泡形状的影响。发现囊泡的形状受κ和εVP的影响。观察到了囊泡的典型形状，如圆形、雪茄状、双囊泡状和球拍状。设计囊泡形状转变有助于开发囊泡几何形状的丰富性以用于期望的应用。
