澳门总统平台:最终的状态图预测了局部内力产生各种膜形状的条件

这种变形囊泡形态的受控实现可以改善诸如小型软体机器人和合成细胞等人工系统的设计,隶属于施普林格自然出版集团,创刊于1869年,从而产生复杂的结构, whereas at high volume fractions globally deformed vesicle shapes are observed. The resulting state diagram predicts the conditions under which local internal forces generate various membrane shapes. A controlled realization of such distorted vesicle morphologies could improve the design of artificial systems such as small-scale soft robots and synthetic cells.

but the realization of a minimal system with localized active internal forces that can strongly deform lipid membranes from within and lead to dramatic shape changes remains challenging. Here we present a combined experimental and simulation study that demonstrates how self-propelled particles enclosed in giant unilamellar vesicles can induce a plethora of non-equilibrium shapes and active membrane fluctuations.
