Advances in colloidal synthesis allow for the design of particles with controlled patches. This article reviews routes towards colloidal locomotion, where energy is consumed and converted into motion, and its implementation with active patchy particles. A special emphasis is given to phoretic swimmers, where the self-propulsion originates from an interfacial phenomenon, raising experimental challenges and opening up opportunities for particles with controlled anisotropic surface chemistry and novel behaviors.

Eppur si muove，但它动起来了：短发（隐喻）游泳者

胶体合成的进展允许设计具有受控贴剂的颗粒。本文回顾了胶体运动的途径，其中能量被消耗并转化为运动，以及其在活性斑块中的实现方式。电泳游泳者特别强调，其中自我推进源自界面现象，这增加了实验挑战，并为具有受控的各向异性表面化学和新行为的粒子提供了机会。
