...The magnitude of the dipole moment depends on the polarizability of the particle, and this in turn is governed by the dielectric properties of the particle and the medium (Pohl, 1978; Jones, 1995)....

...Generally at field strengths in the range of 10 5 to 10(6) Vm(21), our observations indicate that although these forces are present and give rise to fluid motion, the influence is less than the dielectrophoretic force acting on the particles (Ramos et al., 1998)....

...Thermal equilibrium is achieved rapidly, within 1 ms of application of the electric field (Ramos et al., 1998), and both calculations and measurements show that for low conductivity media the steady-state temperature rise is small and not sufficient to denature biological samples....

...Generally at field strengths in the range of 105 to 106 Vm21, our observations indicate that although these forces are present and give rise to fluid motion, the influence is less than the dielectrophoretic force acting on the particles (Ramos et al., 1998)....

...Although natural convection is negligible (Ramos et al., 1998), the high electric field gives rise to volume forces on the liquid (the electrothermal force)....

...As an example, it has been shown that for the simple case of an interdigitated electrode geometry in contact with a medium of conductivity 0.01 Sm21 (with 20 V peak to peak applied), the steady-state temperature rise can be calculated to be 6°C (Ramos et al., 1998)....
