标题： Using microswimmers for particle separation

摘要： 显微自推进游泳器能够通过复杂环境进行自主导航，为微小和纳米级物体的定位、抓取和输送提供了有吸引力的机会。 受运动细胞和细菌的启发，已经制造出人工微游泳器，并在有图案的环境中对其运动进行了实验研究。 我们提议使用由光照射的微游泳器——Janus球体——作为“驱动剂”，在胶体粒子的二元混合物中移动。 我们证明可以通过这种方式有效地分离二元混合物。 我们分析了不同的分离区域。 我们的发现可能在各种生物和医学应用中有所帮助。 显示英文摘要

摘要： Microscopic self-propelled swimmers capable of autonomous navigation through complex environments provide appealing opportunities for localization, pick-up and delivery of micro-and nanoscopic objects. Inspired by motile cells and bacteria, man-made microswimmers have been created, and their motion was studied experimentally in patterned surroundings. We propose to use the microswimmers - Janus spheres illuminated by light - as "driving agents" that move through a binary mixture of colloidal particles. We demonstrate that binary mixtures can be effectively separated in this way. We analyze different regimes of separation. Our finding could be of use for various biological and medical applications.
