Dielectrophoretic Force Equilibrium of Complex Particles
(American Physical Society, 2020)
In contrast to the commonly used spherical Janus particles, here we use engineered Janus particles that are fabricated by means of the photolithography technique for precise control over their geometry and coated regions. ...

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 ...

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 ...

Stationary Electro-osmotic Flow Driven by ac Fields around Insulators
(American Physical Society, 2021)
Electric fields are commonly used for manipulating particles and liquids in microfluidic systems. In this work, we report stationary electro-osmotic flow vortices around dielectric micropillars induced by ac electric fields ...
