Wall Repulsion during Electrophoresis: Testing the Theory of Concentration-Polarization Electroosmosis
(AIP Publishing, 2023)
We experimentally study the repulsion of charged microscopic particles with the channel walls during electrophoresis in microfluidic devices. For low frequencies of the electric fields (< 10 kHz), this repulsion is mainly ...

Combining DC and AC electric fields with deterministic lateral displacement for micro- And nano-particle separation
(American Institute of Physics, 2019)
This paper describes the behavior of particles in a deterministic lateral displacement (DLD) separation device with DC and AC electric fields applied orthogonal to the fluid flow. As proof of principle, we demonstrate ...

Scattering of Metal Colloids by a Circular Post under Electric Fields
(MDPI, 2023)
We consider the scattering of metal colloids in aqueous solutions by an insulating circular post under the action of an AC electric field. We analyze the effects on the particle of several forces of electrical origin: the ...

Wall Repulsion of Charged Colloidal Particles during Electrophoresis in Microfluidic Channels
(American Physical Society, 2022)
Electrophoresis describes the motion of charged particles suspended in electrolytes when subjected to an external electric field. Previous experiments have shown that particles undergoing electrophoresis are repelled from ...
