Abstract

The requirements for the precise control and manipulation of particles in microfluidics were identified by positive dielectrophoresis. The conditions under which the interparticle electric interactions do not affect the particle trapping in the high-field strength regions were identified. The results showed the existence of a lower bound on the scale of the microelectrodes, below which the expected improvement in positioning the particles in the preselected locations cannot be attained.
