Here we show that chemically propelled micro-rods can be captured, with little change in their speed, into close orbits around solid spheres resting on or near a horizontal plane. We show that this interaction between sphere and particle is short-range, occurring even for spheres smaller than the particle length, and for a variety of sphere materials. We consider a simple model, based on lubrication theory, of a force- and torque-free swimmer driven by a surface slip (the phoretic propulsion mechanism) and moving near a solid surface. The model demonstrates capture, or movement towards the surface, and yields speeds independent of distance. This study reveals the crucial aspects of activity–driven interactions of self-propelled particles with passive objects, and brings into question the use of colloidal tracers as probes of active matter.","lang":"eng"}],"year":"2014","date_published":"2014-03-21T00:00:00Z","volume":10,"quality_controlled":"1","pmid":1,"scopus_import":"1","title":"Hydrodynamic capture of microswimmers into sphere-bound orbits","citation":{"mla":"Takagi, Daisuke, et al. “Hydrodynamic Capture of Microswimmers into Sphere-Bound Orbits.” <i>Soft Matter</i>, vol. 10, no. 11, 1784, Royal Society of Chemistry , 2014, doi:<a href=\"https://doi.org/10.1039/c3sm52815d\">10.1039/c3sm52815d</a>.","ista":"Takagi D, Palacci JA, Braunschweig AB, Shelley MJ, Zhang J. 2014.
