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:

Dielectrophoretic Traps for Efficient Bead and Cell Trapping and Formation of Aggregates of Controlled Size and Composition
Clémentine Sophie Sarah Lipp,Laure Koebel,Arnaud Bertsch,Michaël Gauthier,Aude Bolopion,Philippe Renaud +5 more
TL;DR: A novel method is proposed to characterize the efficiency of the dielectrophoretic trapping, considering the flow speed but also the heat generated by the traps as limiting criteria in cell-safe manipulation.
Dielectrophoresis based methods for separating particles on lab-on-chip platforms
TL;DR: The presented methodology and its implementation have the potential to serve as the basis for a new class of point-of-care, portable diagnostic devices by allowing researchers to sort and assay particles of interest based on their structure and composition without the use of expensive and destructive biochemical labeling techniques.

Application of PIV to AC Electrokinetic Flow
TL;DR: Micron-Resolution Particle Image Velocimetry (μ-PIV) is used to determine uniquely the fluid velocity from observation of particle s without a priori knowledge of the electrical properties.

Glass integrated optofluidic sensor exploiting dielectrophoresis for label-free detection of bacterial viability
TL;DR: In this article , the authors proposed an integrated opto-fluidic sensor which sorts and quantifies the dead or alive bacteria in a liquid sample by a selective trapping of the bacteria exploiting dielectrophoretic effects.

Railing Nanoparticles Along Activated Tracks Towards Continuous-Flow Electrokinetic Enrichment from Blood Plasma *
TL;DR: A unique microfluidic device is reported that can enrich nanoparticles in a continuous flow by railing them along activated tracks (electrodes) based on dielectrophoretic force and electrohydrodynamic drag in both low and high conductive media.

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.
