Separation of Submicron Bioparticles by Dielectrophoresis
TLDR
With electrode arrays fabricated using direct write electron beam lithography, it is shown that different types of submicron latex spheres can be spatially separated and it is demonstrated that tobacco mosaic virus and herpes simplex virus can be manipulated and spatially separation in a microelectrode array.About:

On-Chip Concentration and Patterning of Biological Cells Using Interplay of Electrical and Thermal Fields
TL;DR: The efficacy of the cell trapping process for two different biological entities, namely, Escherichia coli bacteria and yeast cell are characterized and have importance towards developing biomedical microdevices for drug discovery, antibiotic resistance assessment and medical diagnostics.
Journal ArticleDOI
Tunable aqueous virtual micropore.
TL;DR: A charged microparticle can be trapped in an aqueous environment by forming a narrow virtual pore--a cylindrical space region in which the particle motion in the radial direction is limited by forces emerging from dynamical interactions of the particle charge and dipole moment with an external radiofrequency quadrupole electric field.
Journal ArticleDOI
Separation characteristics of animal cells using a dielectrophoretic filter.
TL;DR: The separation characteristics of a wire–wire type dielectrophoretic filter were evaluated using animal cells and it becomes clear that the specific growth rate of the cells of the retention liquid was higher than that of the Cells of the permeation liquid.

Electrodeless Dielectrophoretic Trapping and Separation of Cells
TL;DR: Using electrodeless dielectrophoretic (EDEP) traps fabricated with silicone elastomer, in the contrary of the commonly used metallic DEP traps, this article demonstrated trapping of bacterial cells E. Coli (positive DEP) and its separation from blood cells (negative DEP).

Electromechanics of Particles
TL;DR: In this paper, a detailed account of the electromechanical interactions that govern the behaviour of small particles when an electric or magnetic field is present is presented, with numerous real-world examples.

Ac electrokinetics: a review of forces in microelectrode structures
TL;DR: In this article, the frequency dependency and magnitude of electrothermally induced fluid flow are discussed for low frequencies (up to 500 kHz) and the effects of Brownian motion, diffusion and buoyancy force are discussed in the context of the controlled manipulation of sub-micrometre particles.
Journal ArticleDOI
The Motion and Precipitation of Suspensoids in Divergent Electric Fields
TL;DR: In this article, it was shown that the phenomena of dielectrophoresis and dielectro-precipitation can be observed under rather ideal conditions, though it is ordinarily often difficult to do so because of the presence of the more easily produced electrophoreis or ion-type migration of charged particles.
