Biomimetic cross-linked polymersomes that exhibit a self-beating motion without any on-off switching are developed. The polymersomes are made from a well-defined synthetic thermoresponsive diblock copolymer, and the thermoresponsive segment includes ruthenium catalysts for the oscillatory chemical reaction and vinylidene groups to cross-link the polymersomes. Autonomous volume and shape oscillations of the cross-linked polymersomes are realized following redox changes of the catalysts.
制备了一种仿生交联聚合物囊泡,其无需任何开-关切换即可表现出自发的拍打运动。该聚合物囊泡由结构明确的合成温度响应性两亲性嵌段共聚物制成,其中温度响应性嵌段包含钌催化剂用于振荡化学反应和亚乙烯基基团用于交联聚合物囊泡。交联聚合物囊泡的自主体积和形状振荡是通过催化剂的氧化还原变化来实现的。
