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:

Using nonuniform electric fields to accelerate the transport of viruses to surfaces from media of physiological ionic strength.

TL;DR: It is suggested that ac electrokinetic phenomena can be used to expeditiously transport and capture viruses onto surfaces from solutions of high ionic strength, thus providing a potentially useful approach to addressing a bottleneck in the development of devices that allow for rapid sampling and detection of infectious biological agents.

Constantin Lefter,Constantin Lefter,Reasmey P. Tan,Simon Tricard,Julien Dugay,Gábor Molnár,Lionel Salmon,Julian Carrey,Aurelian Rotaru,Azzedine Bousseksou +9 more
TL;DR: In this paper, the integration of micro-rods of the [Fe(Htrz)2(trz)](BF4) spin crossover compound into an electronic switch-type device was reported.
Journal ArticleDOI
Dielectrophoretic behavior of latex nanospheres: low-frequency dispersion.
TL;DR: It is suggested that an additional, anomalous polarization mechanism observed in media of high conductivity, causing an unexpected observation of positive dielectrophoresis, may be explained in terms of the polarization of the Stern layer.

Refinement of insulator-based dielectrophoresis
Claire V. Crowther,Mark A. Hayes +1 more
TL;DR: The improved design includes a unique new multi-length scale structure that streamlines the analyte(s) and improves homogeneity in the lateral dimension, while still achieving high gradients necessary for analyte separation using DEP.
Journal ArticleDOI
Selective capture of a specific cell type from mixed leucocytes in an electrode-integrated microfluidic device.
TL;DR: By immobilizing neutrophil- or eosinophil-specific antibodies onto the created region, it is demonstrated that the corresponding leucocyte type can be captured from the concentrated leucocytes.

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.

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.
