Numerical simulation of dielectrophoresis

Separation and deposition of cells and particles are of great
interests in analytical chemistry, and dielectrophoresis (DEP) separation
has been demonstrated to be feasible with high selectivity  
and simplicity. DEP force describes the force exerted on uncharged  
dielectric particles due to the difference between the polarizability of
medium and particles.

In this talk, a popularly used model, the so-called effective dipole moment
method is introduced. Based on this model, applications of DEP separation on
bio-cells and carbon nanotubes have been performed. We also investigate the fluid
dynamical phenomenon, electrothermal flow, appearing in the DEP environment.
