Abstract

The motion and segregation of positively polarized particles flowing through dielectrophoretic microfluidics were studied. Experiments were conducted on microfluidics with electrodes of different sizes arranged perpendicular and parallel to the flow. It was demonstrated that the presence of the interparticle dipolar interactions imposes a lower bound on the size of the electrodes below which the miniaturization of microelectrodes adversely affects the ability to position the particles with precision in preselected locations.
