Self-propelled droplets made of organic materials can be an influential candidate for understanding cell migration from the viewpoint of nonequilibrium physics and have attracted significant attention with regard to soft-matter-type rovers. Because self-propelled droplets are soft enough to be easily deformed, they should be useful as chemically artificial rovers that can move in small areas with many obstacles in water and can be applied as ‘motile’ carriers for exploring and curing of biological bodies or remediation of the natural environment. Here, we review recent research progress on designing self-propelled droplets of micrometer size.

在微米级环境下基于自走液滴的化学人工流动车

从非平衡物理的角度来看，由有机材料制成的自推进液滴可以成为理解细胞迁移的有力候选者，并且在软物质型流动车方面引起了极大的关注。由于自走式液滴足够柔软以至于不易变形，因此它们应作为化学人工流动车使用，可以在水中有很多障碍的小区域移动，并可以用作“活动”载体，以探索和固化生物体或进行补救自然环境。在这里，我们回顾了最近在设计微米大小的自驱动液滴的研究进展。
