Colloidal particles are propelled in a nematic liquid crystal via application of an alternating current electric field. Swarms of particles are assembled into a rotating mill cluster, or moved as a whole along predefined paths photo-imprinted on chemically functionalized substrates. This technique represents an alternative approach to fluid based lab-on-a-chip technologies guiding the motion of large ensembles of micrometer scale solid or liquid inclusions.5 p.application/pdfeng(c) IEEE, 2015Col·loidesCristalls líquidsMicrofluídicaColloidsLiquid crystalsMicrofluidicsinfo:eu-repo/semantics/article6523632015-10-09info:eu-repo/semantics/openAccess25622322
