Dielectrophoresis of macromolecules
Biopolymers, 1973AbstractDilute solutions of rigid helical macromolecules with permanent dipole moments have been studied with dielectrophoresis. The polymers used were poly‐γ‐benzyl‐L‐glutmate and poly‐n‐butyl isocyanate, both fractions of average molecular weight 120,000.

Multiple frequency dielectrophoresis
ELECTROPHORESIS, 2007AbstractA novel method of modeling multiple frequency dielectrophoresis (MFDEP) is introduced based on the concept of an effective Clausius–Mossotti factor, CMeff, for a particle that is exposed to electrical fields of different frequencies, coming either from one or multiple pairs of electrodes. This analysis clearly illustrates how adding frequencies

Floating electrode dielectrophoresis
ELECTROPHORESIS, 2006AbstractIn practice, dielectrophoresis (DEP) devices are based on micropatterned electrodes. When subjected to applied voltages, the electrodes generate nonuniform electric fields that are necessary for the DEP manipulation of particles. In this study, electrically floating electrodes are used in DEP devices.

The force due to polarization exerted on dielectric particles, vapor or gas bubbles, and voids in insulating dielectric liquids is an example of dielectrophoresis. This force is directly proportional to the gradient of the electric field intensity.

Self-assembly of nanoparticles into microscale patterns by spray deposition and dielectrophoresis is investigated using microfabricated RF traps and nanospheres visualized using confocal fluorescence microscopy. Different combinations of spraying mode and trapping field lead to different results.

Abstract Dielectrophoresis (DEP) is the movement of a charge-neutral particle in a fluid induced by an inhomogeneous electric field. This driving field can be either DC or AC, see Jones (1995). We begin our analysis by considering a DC field E.

Dielectrophoresis describes neutral particles moving in non-uniform electric fields. We experimentally observe the dielectrophoresis of gas generated by macroscopic electrodes and show that this effect can be large enough to generate audible sound. The observed sound agrees with a multiscale model of dielectrophoresis of gas.

Protein Dielectrophoresis in Solution
The Journal of Physical Chemistry B, 2018Proteins experience either pulling or repelling force from the gradient of an external electric field due to the effect known as dielectrophoresis (DEP). The susceptibility to the field gradient is traditionally calculated from the solution of the electrostatic boundary-value problem, which requires assigning a dielectric constant to the protein.

A unified theory of dielectrophoresis and travelling wave dielectrophoresis
Journal of Physics D: Applied Physics, 1994We show for the first time that a particle in a non-uniform AC electric field experiences a dielectrophoretic force arising from spatial non-uniformities of the magnitude and phase of the field interacting, respectively, with the in-phase and out-of-phase components of the induced dipole moment.

Molecular dielectrophoresis of bio-polymers
Conference Record of the 1992 IEEE Industry Applications Society Annual Meeting, 1994Dielectrophoresis (DEP) has found wide applications in manipulations of micrometer-sized particles such as biological cells. However, it has been considered less effective for nanometer-sized particles such as biological macromolecules where DEP effects may be overwhelmed by Brownian motion.
