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:

Manipulating nanoparticles in solution with electrically contacted nanotubes using dielectrophoresis.
TL;DR: This work shows that this restriction can be overcome by using the large electric field gradient in the vicinity of a carbon nanotube to electronically manipulate nanoparticles down to 2 nm in diameter.

Alternating current electrokinetic separation and detection of DNA nanoparticles in high‐conductance solutions
TL;DR: AC electric field conditions have been found which allow the separation of DNA nanoparticles to be achieved under high‐conductance (ionic strength) conditions, and may allow AC electrokinetic systems to be developed that can be used with clinically relevant samples under physiological conditions.
Journal ArticleDOI
Quantitative Analysis of Gold Nanorod Alignment after Electric Field-Assisted Deposition
TL;DR: It is found that hydrodynamic interactions and capillary effects during drying, as well as friction of nanorods on the substrate surface, to not play a major role, and the degree of alignment is considerably smaller than what was previously reported for field-induced nanorod alignment in suspension.

Synergism between particle-based multiplexing and microfluidics technologies may bring diagnostics closer to the patient
Stefaan Derveaux,Barbara Stubbe,Kevin Braeckmans,Christian Hubert Simon Roelant,Kae Sato,Joseph Demeester,S.C. De Smedt +6 more
TL;DR: This review aims to debate on the “added value” the authors can expect from (bio)analysis with particles in microfluidic devices and special emphasis is placed on the challenges of integrating currently existing detection platforms for encoded microparticles into microdevices.

TL;DR: A microfabricated fluorescence-activated cell sorter system using a thermoreversible gelation polymer (TGP) as a switching valve is developed and the sorting of fluorescent microspheres and Escherichia coli cells expressing fluorescent proteins is demonstrated.

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.
