Generally, multiphase AC electric fields and quadrupolar electrode configuration are needed to create a rotating electric field for electrorotation. In this study, we demonstrate a simple method to rotate dielectrophoretically trapped microparticles using a stationary AC electric field. Coplanar interdigitated electrodes are used to create a linearly polarized nonuniform AC electric field. This nonuniform electric field is employed for dielectrophoretic trapping of microparticles as well as for generating electroosmotic flow in the vicinity of the electrodes resulting in rotation of microparticles in a microfluidic device. The rotation of barium titanate microparticles is observed in 2-propanol and methanol solvent at a frequency below 1\u2009kHz. A particle rotation rate as high as 240 revolutions per minute is observed. It is demonstrated that precise manipulation (both rotation rate and equilibrium position) of the particles is possible by controlling the frequency of the applied electric field. At low frequency range, the equilibrium positions of the microparticles are observed between the electrode edge and electrode center. This method of particle manipulation is different from electrorotation as it uses induced AC electroosmosis instead of electric torque as in the case of electrorotation. Moreover, it has been shown that a microparticle can be rotated along its own axis without any translational motion.<\/jats:p>","DOI":"10.1063\/1.4943032","type":"journal-article","created":{"date-parts":[[2016,3,2]],"date-time":"2016-03-02T18:00:52Z","timestamp":1456941652000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":26,"title":["Combined AC electroosmosis and dielectrophoresis for controlled rotation of microparticles"],"prefix":"10.1063","volume":"10","author":[{"given":"Md.","family":"Walid Rezanoor","sequence":"first","affiliation":[{"name":"Washington State University School of Mechanical and Materials Engineering, , Pullman, Washington 99164-2920, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Prashanta","family":"Dutta","sequence":"additional","affiliation":[{"name":"Washington State University School of Mechanical and Materials Engineering, , Pullman, Washington 99164-2920, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"317","published-online":{"date-parts":[[2016,3,2]]},"reference":[{"issue":"5","key":"2023070515330648900_c1","doi-asserted-by":"publisher","first-page":"051405","DOI":"10.1103\/PhysRevE.67.051405","volume":"67","year":"2003","journal-title":"Phys.
