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."}],"date_published":"2014-03-21T00:00:00Z","publication_identifier":{"eissn":["1744-6848"],"issn":["1744-683X"]},"issue":"11","oa_version":"Preprint","author":[{"last_name":"Takagi","full_name":"Takagi, Daisuke","first_name":"Daisuke"},{"orcid":"0000-0002-7253-9465","id":"8fb92548-2b22-11eb-b7c1-a3f0d08d7c7d","full_name":"Palacci, Jérémie A","first_name":"Jérémie A","last_name":"Palacci"},{"first_name":"Adam B.","full_name":"Braunschweig, Adam B.","last_name":"Braunschweig"},{"last_name":"Shelley","full_name":"Shelley, Michael J.","first_name":"Michael J."},{"last_name":"Zhang","full_name":"Zhang, Jun","first_name":"Jun"}],"intvolume":"        10","oa":1,"article_processing_charge":"No","day":"21","scopus_import":"1","type":"journal_article","publication":"Soft Matter","external_id":{"pmid":["24800268"],"arxiv":["1309.5662"]},"_id":"9050","article_type":"original","status":"public","volume":10,"title":"Hydrodynamic capture of microswimmers into sphere-bound orbits","article_number":"1784","date_created":"2021-02-01T13:43:31Z","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1309.5662"}],"publisher":"Royal Society of Chemistry ","quality_controlled":"1","publication_status":"published","language":[{"iso":"eng"}],"month":"03","citation":{"ieee":"D.
