Self-propelled particles are known to accumulate in the proximity of walls. Here we show how fast particles expel slower ones from the wall leading to a segregated state. The mechanism is understood as a function of particle velocities, particle density, or channel width. In the presence of an external fluid flow, particles with two different velocities segregate due to their different particle fluxes. Promising applications can be found in the development of microfluidic lab-on-a-chip devices for sorting of particles with different motilities. 000154822 536__ $$0G:(DE-HGF)POF2-451$$a451 - Soft Matter Composites (POF2-451)$$cPOF2-451$$fPOF II$$x0 000154822 588__ $$aDataset connected to CrossRef, juser.fz-juelich.de 000154822 7001_ $$0P:(DE-Juel1)130629$$aElgeti, Jens$$b1$$ufzj 000154822 7001_ $$0P:(DE-Juel1)130514$$aAuth, Thorsten$$b2$$ufzj 000154822 7001_ $$0P:(DE-Juel1)130665$$aGompper, Gerhard$$b3$$ufzj 000154822 7001_ $$0P:(DE-Juel1)130920$$aRipoll, Marisol$$b4$$ufzj 000154822 773__ $$0PERI:(DE-600)1465366-7$$a10.1209/0295-5075/107/36003$$gVol. 107, no. 3, p. 36003 -$$n3$$p36003 -$$tepl$$v107$$x1286-4854$$y2014 000154822 8564_ $$uhttps://juser.fz-juelich.de/record/154822/files/FZJ-2014-04090.pdf$$yRestricted 000154822 8564_ $$uhttps://juser.fz-juelich.de/record/154822/files/1409.1417.pdf$$yOpenAccess 000154822 8564_ $$uhttps://juser.fz-juelich.de/record/154822/files/FZJ-2014-04090.pdf?subformat=pdfa$$xpdfa$$yRestricted 000154822 8564_ $$uhttps://juser.fz-juelich.de/record/154822/files/1409.1417.pdf?subformat=pdfa$$xpdfa$$yOpenAccess 000154822 909CO $$ooai:juser.fz-juelich.de:154822$$pdnbdelivery$$pdriver$$pVDB$$popen_access$$popenaire 000154822 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)145529$$aForschungszentrum Jülich GmbH$$b0$$kFZJ 000154822 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)130629$$aForschungszentrum Jülich GmbH$$b1$$kFZJ 000154822 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)130514$$aForschungszentrum Jülich GmbH$$b2$$kFZJ 000154822 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)130665$$aForschungszentrum Jülich GmbH$$b3$$kFZJ 000154822 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)130920$$aForschungszentrum Jülich GmbH$$b4$$kFZJ 000154822 9132_ $$0G:(DE-HGF)POF3-551$$1G:(DE-HGF)POF3-550$$2G:(DE-HGF)POF3-500$$aDE-HGF$$bKey Technologies$$lBioSoft Fundamentals for future Technologies in the fields of Soft Matter and Life Sciences$$vFunctional Macromolecules and Complexes$$x0 000154822 9131_ $$0G:(DE-HGF)POF2-451$$1G:(DE-HGF)POF2-450$$2G:(DE-HGF)POF2-400$$3G:(DE-HGF)POF2$$4G:(DE-HGF)POF$$aDE-HGF$$bSchlüsseltechnologien$$lBioSoft$$vSoft Matter Composites$$x0 000154822 9141_ $$y2014 000154822 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000154822 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR 000154822 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000154822 915__ $$0StatID:(DE-HGF)0110$$2StatID$$aWoS$$bScience Citation Index 000154822 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000154822 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000154822 915__ $$0StatID:(DE-HGF)0020$$2StatID$$aNo Peer review 000154822 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline 000154822 915__ $$0StatID:(DE-HGF)1020$$2StatID$$aDBCoverage$$bCurrent Contents - Social and Behavioral Sciences 000154822 915__ $$0StatID:(DE-HGF)0420$$2StatID$$aNationallizenz 000154822 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bThomson Reuters Master Journal List 000154822 9201_ $$0I:(DE-Juel1)IAS-2-20090406$$kIAS-2$$lTheorie der Weichen Materie und Biophysik$$x0 000154822 9201_ $$0I:(DE-Juel1)ICS-2-20110106$$kICS-2$$lTheorie der Weichen Materie und Biophysik$$x1 000154822 9801_ $$aFullTexts 000154822 980__ $$ajournal 000154822 980__ $$aVDB 000154822 980__ $$aUNRESTRICTED 000154822 980__ $$aI:(DE-Juel1)IAS-2-20090406 000154822 980__ $$aI:(DE-Juel1)ICS-2-20110106 000154822 981__ $$aI:(DE-Juel1)IBI-5-20200312 000154822 981__ $$aI:(DE-Juel1)IAS-2-20090406 000154822 981__ $$aI:(DE-Juel1)ICS-2-20110106
