Electrokinetic wall effect mechanisms and applications
(2020) 24th International Conference on Miniaturized Systems for Chemistry and Life Sciences, MicroTAS 2020 In MicroTAS 2020 - 24th International Conference on Miniaturized Systems for Chemistry and Life Sciences p.42-43- Abstract
Under the application of longitudinal electric fields in microchannels, microparticles experience lift forces that push them away from the channel walls and affect their trajectories. At high frequencies (>100KHz) the dielectrophoretic forces dominate and are well understood but at lower frequencies there is little agreement as to the exact nature of the forces, how they are generated and how they vary due to the many different experimental conditions that are used in microfluidics devices. Here we present an experimental study of these mechanisms.
