Short communication: A simple and accurate method of measuring the zeta-potential of microfluidic channels
(Wiley-Blackwell, 2021)
We describe an improved method for determining the electroosmotic mobility and zeta potential of surfaces based on a current-monitoring method. This technique eliminates the requirement for measurements of channel dimensions ...

Dipolophoresis and Travelling-Wave Dipolophoresis of Metal Microparticles
(MDPI, 2020)
We study theoretically and numerically the electrokinetic behavior of metal microparticles immersed in aqueous electrolytes. We consider small particles subjected to non-homogeneous ac electric fields and we describe their ...

Particle Finder: a Simple Particle Detection Tool for Continuous-flow Systems
(Springer Nature, 2023)
We describe a user-friendly, open source software for single-particle detection/counting in a continuous-flow. The tool automatically processes video images of particles, including pre-conditioning, followed by size-based ...

Insulating Traveling-wave Electrophoresis
(American Physical Society, 2023)
Traveling-wave electrophoresis (TWE) is a method for transporting charged colloidal particles used in many microfluidic techniques for particle manipulation and fractionation. This method exploits the traveling-wave ...

Electrokinetic Biased Deterministic Lateral Displacement: Scaling Analysis and Simulations
(Elsevier, 2020)
Deterministic Lateral Displacement (DLD) is a microfluidic technique where arrays of micropillars within a microchannel deflect particles leading to size-based segregation. We recently demonstrated that applying AC electric ...

Stationary electro-osmotic flow driven by AC fields around charged dielectric spheres
(Cambridge University Press, 2021)
We experimentally demonstrate quadrupolar electro-osmotic flows around charged dielectric microspheres immersed in an electrolyte when subjected to an alternating current electric field. We present an electrokinetic model ...
