Translating energy into swarming motion for miniature entities remains a challenge. This translation requires simultaneously breaking the symmetry of the system to enable locomotion and a coupling effect between the objects that are part of the population to induce the collective motion. Here, we report on Robocoliths, engineered Emiliania huxleyi (EHUX) coccolith-based miniature hybrid entities capable of swarming behavior. EHUX coccoliths are characterized by an asymmetric morphology that allows breaking symmetry, playing a central role in generating a net force and directed motion. Their activation with the bioinspired material polydopamine not only endows the asymmetric coccoliths with advanced functionalities, such as thermal- and energy-harvesting responsiveness under visible light exposure to display a collective behavior (i.e., swarming), but it also provides a functional surface from which antifouling polymer brushes are grown. In this context, Robocoliths pave the way for the next generation of multifunctional swarming bio-micromachines.

基于可可脂的工程混合动力车,可将光转换为蜂拥而至的运动

将能量转化为微型实体的蜂群运动仍然是一个挑战。这种平移需要同时破坏系统的对称性,以实现运动以及作为总体一部分的物体之间的耦合效应,以引起集体运动。在这里,我们报道了Robocoliths,Emiliaania huxleyi(EHUX)基于cococolith的微型混合实体,这些群体具有泛滥行为。H球石的特征是不对称形态,可以破坏对称性,在产生净力和定向运动中起着核心作用。它们被生物启发性材料聚多巴胺激活,不仅赋予不对称cococoliths先进的功能,例如在可见光下的热能和能量收集响应能力,以表现出集体行为(例如,蜂拥而至),而且还提供了功能性表面生长了防污聚合物刷。在这种情况下,Robocoliths为下一代多功能群集生物微机铺平了道路。
