We show that the motion of active, self-propelled colloids can be sufficiently controlled for use as a tool to assemble complex structures such as braids and weaves out of microscopic filaments. Unlike typical self-assembly paradigms, these structures are held together by geometric constraints rather than adhesive bonds. The out-of-equilibrium assembly that we propose involves precisely controlling the 2D motion of active colloids so that their path has a nontrivial topology. We demonstrate with proof-of-principle Brownian dynamics simulations that, when the colloids are attached to long semiflexible filaments, this motion causes the filaments to braid. The ability of the active particles to provide sufficient force necessary to bend the filaments into a braid depends on a number of factors, including the self-propulsion mechanism, the properties of the filament, and the maximum curvature in the braid. Our work demonstrates that nonequilibrium assembly pathways can be designed using active particles.","lang":"eng"}],"oa_version":"None","issue":"2","publication_status":"published","publication":"Proceedings of the National Academy of Sciences","title":"Using active colloids as machines to weave and braid on the micrometer scale","quality_controlled":"1","author":[{"id":"EB352CD2-F68A-11E9-89C5-A432E6697425","last_name":"Goodrich","orcid":"0000-0002-1307-5074","first_name":"Carl Peter","full_name":"Goodrich, Carl Peter"},{"last_name":"Brenner","full_name":"Brenner, Michael P.","first_name":"Michael P."}],"doi":"10.1073/pnas.1608838114","_id":"7758"}
