DNA dielectrophoresis: Theory and applications a review

Electrophoresis, 2017
Dielectrophoresis is the migration of an electrically polarizable particle in an inhomogeneous electric field. This migration can be exploited for several applications with (bio)molecules or cells. Dielectrophoresis is a noninvasive technique; therefore,

Dielectrophoresis of Nanoparticles

Fluids Engineering, 2004
A numerical scheme based on the distributed Lagrange multiplier method (DLM) is used to study the motion of nano sized particles of dielectric suspensions subjected to uniform and nonuniform electric fields. Particles are subjected to both electrostatic and hydrodynamic forces, as well as Brownian motion.

Dielectrophoresis of chloroplasts

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1971
Abstract Dielectrophoresis is the migration of neutral particles in a nonuniform electric field (a.c. or d.c.) toward the region of highest field intensity. Dielectrophoresis should be distinguished from electrophoresis which is the migration of charged particles in electric fields.

Dielectrophoresis of macromolecules

Biopolymers, 1973
AbstractDilute 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.

Applications of dielectrophoresis in biotechnology

Trends in Biotechnology, 1997
Recent progress in the development of microelectrode structures has led to new techniques for the dielectrophoretic characterization and sorting of cells, microorganisms and other bioparticles using nonuniform AC electric fields. These methods utilize differences in the dielectric polarizabilities of cells for their effectiveness, and factors ...

Dielectrophoresis of Proteins in Solution

The Journal of Physical Chemistry B, 2020
A nonionic particle placed in the gradient of an electric field experiences the dielectrophoretic force which scales linearly with the gradient of the electric field squared. The proportionality constant is the dielectrophoretic susceptibility, that is, a linear transport coefficient. For proteins in solution, it is mostly affected by the following two

Multiple frequency dielectrophoresis

ELECTROPHORESIS, 2007
AbstractA 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

Trapping of DNA by dielectrophoresis

ELECTROPHORESIS, 2002
Under suitable conditions, a DNA molecule in solution will develop a strong electric dipole moment. This induced dipole allows the molecule to be manipulated with field gradients, in a phenomenon known as dielectrophoresis (DEP). Pure dielectrophoretic motion of DNA requires alternate current (AC) electric fields to suppress the electrophoretic effect ...

Moving pulsed dielectrophoresis

Lab on a Chip, 2013
In this paper, we introduce a dielectrophoresis (DEP)-based handling method that allows fine 3D manipulation of beads in suspension using a lab on a chip device. The device consists of two layers of linear electrodes on the top and bottom of a microfluidic channel.
