Asymmetric channel geometry was designed to apply additional inertial forces besides lift forces to promote laterally ordered particles to achieve sheathless focusing or size-dependent sorting. The evolving hydrodynamic forces were tailored with altered channel parameters (width and height), and different flow rates, to get a better understanding of smaller beads\u2019 lateral migration. Fluorescent beads (with the diameter of 4.8 \u00b5m and 15.8 \u00b5m) were used to distinguish the focusing position in continuous flow, and experimental results were compared to in silico models for particle movement prediction, made in COMSOL Multiphysics. The focusing behaviour of the applied microfluidic system was mainly characterised for particle size in the range close to blood cells and bacteria.<\/jats:p>","DOI":"10.3390\/s22093474","type":"journal-article","created":{"date-parts":[[2022,5,3]],"date-time":"2022-05-03T08:26:35Z","timestamp":1651566395000},"page":"3474","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Geometry-Dependent Efficiency of Dean-Flow Affected Lateral Particle Focusing and Separation in Periodically Inhomogeneous Microfluidic Channels"],"prefix":"10.3390","volume":"22","author":[{"given":"Anita","family":"B\u00e1nyai","sequence":"first","affiliation":[{"name":"Microsystems Laboratory, Centre for Energy Research, Institute of Technical Physics and Materials Science, ELKH, Konkoly Thege Mikl\u00f3s Str. 29-33, H-1121 Budapest, Hungary"},{"name":"77 Elektronika Ltd., Feh\u00e9rv\u00e1ri Str. 98, XI., H-1111 Budapest, Hungary"},{"name":"Doctoral School on Materials Sciences and Technologies, \u00d3buda University, B\u00e9csi Str. 96\/B, H-1034 Budapest, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4013-499X","authenticated-orcid":false,"given":"Eszter Leel\u0151ssyn\u00e9","family":"T\u00f3th","sequence":"additional","affiliation":[{"name":"Microsystems Laboratory, Centre for Energy Research, Institute of Technical Physics and Materials Science, ELKH, Konkoly Thege Mikl\u00f3s Str. 29-33, H-1121 Budapest, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M\u00e1t\u00e9","family":"Varga","sequence":"additional","affiliation":[{"name":"77 Elektronika Ltd., Feh\u00e9rv\u00e1ri Str. 98, XI., H-1111 Budapest, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8022-4367","authenticated-orcid":false,"given":"P\u00e9ter","family":"F\u00fcrjes","sequence":"additional","affiliation":[{"name":"Microsystems Laboratory, Centre for Energy Research, Institute of Technical Physics and Materials Science, ELKH, Konkoly Thege Mikl\u00f3s Str. 29-33, H-1121 Budapest, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"209","DOI":"10.1038\/189209a0","article-title":"Radial Particle Displacements in Poiseuille Flow of Suspensions","volume":"189","author":"Segre","year":"1961","journal-title":"Nature"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"2893","DOI":"10.1039\/c1lc20307j","article-title":"Continuous dielectrophoretic bacterial separation and concentration from physiological media of high conductivity","volume":"11","author":"Park","year":"2011","journal-title":"Lab Chip"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"4665","DOI":"10.1039\/C4LC00868E","article-title":"Submicron separation of microspheres via travelling surface acoustic waves","volume":"14","author":"Destgeer","year":"2014","journal-title":"Lab Chip"},{"key":"ref_4","doi-asserted-by":"crossref","first-page":"5657","DOI":"10.1002\/smll.201501820","article-title":"Optimization of Pathogen Capture in Flowing Fluids with Magnetic Nanoparticles","volume":"11","author":"Kang","year":"2015","journal-title":"Small"},{"key":"ref_5","doi-asserted-by":"crossref","first-page":"3656","DOI":"10.1039\/c1lc20653b","article-title":"Enhanced cell sorting and manipulation with combined optical tweezer and microfluidic chip technologies","volume":"11","author":"Wang","year":"2011","journal-title":"Lab Chip"},{"key":"ref_6","doi-asserted-by":"crossref","first-page":"912","DOI":"10.1016\/j.ijheatmasstransfer.2018.12.126","article-title":"Investigation on the thermophoretic sorting for submicroparticles in a sorter with expansion-contraction microchannel","volume":"133","author":"Wang","year":"2019","journal-title":"Int.
