Definition
AC electrokinetics is the name given to a group of techniques that utilize alternating (AC) electric fields to move dielectric particles in suspension. AC electrokinetics of nanoparticles refers to methods of exerting electrical force and/or torque on particles of nanometer dimensions, examples of which are viruses, macromolecules, and colloidal particles.
Introduction
Dielectrics do not bear a net charge but rather polarize when subjected to electric fields. When dielectric particles in suspension are subjected to electric fields, polarization results in charge accumulation at the particle/electrolyte interface. Electrode polarization may also occur, giving rise to the buildup of a double layer of ions and counterions at the electrode/electrolyte interface. Particle polarization is represented by effective dipole and higher-order moments. AC electrokinetic forces and torques...
