Accurate control of the shape transformation of polymersome is an important and interesting challenge that spans across disciplines such as nanomedicine and nanomachine. Here, we report a fast and facile methodology of shape manipulation of polymersome via out-of-equilibrium polymer self-assembly and shape change by chemical addition of additives. Due to its increased permeability, hydrophilicity, and fusogenic properties, poly(ethylene oxide) was selected as the additive for bringing the system out of equilibrium via fast addition into the polymersome organic solution. A new shape, stomatocyte-in-stomatocyte (sto-in-sto), is obtained for the first time. Moreover, fast shape transformation within less than 1 min to other relevant shapes such as stomatocyte and large compound vesicles was also obtained and accurately controlled in a uniform dispersion. This methodology is demonstrated as a general strategy with which to push the assembly further out of equilibrium to generate unusual nanostructures in a controllable and fast manner.

口腔细胞中的口腔细胞：通过化学添加方法诱导的聚合物小体的新形状。
精确控制多聚体的形状转变是一项重要而有趣的挑战，跨越了纳米医学和纳米机械等学科。在这里，我们报告了通过不平衡的聚合物自组装和通过化学添加添加剂来改变形状的聚合物小体的形状操纵的快速而简便的方法。由于其增加的渗透性，亲水性和融合特性，选择了聚环氧乙烷作为添加剂，可通过快速添加到聚合体有机溶液中使系统失去平衡。首次获得一种新形状，即“口腔中的口腔细胞”。而且，还可以在不到1分钟的时间内将形状快速转变为其他相关形状，例如口气细胞和大的复合囊泡，并以均匀的分散体进行精确控制。该方法论已被证明是一种通用策略，通过该策略可将组件进一步推离平衡，从而以可控制的快速方式生成异常的纳米结构。
