Planar hydrodynamic traps and buried channels for bead and cell trapping and releasing

Philippe Renaud, Arnaud Bertsch, Daniel Migliozzi, Clémentine Sophie Sarah Lipp, Jonathan Bastien Cottet

We present a novel concept for the controlled trapping and releasing of beads and cells in a PDMS microfluidic channel without obstacles present around the particle or in the channel. The trapping principle relies on a two-level microfluidic configuration: ...

Positional dependence of particles and cells in microfluidic electrical impedance flow cytometry: origin, challenges and opportunities

Philippe Renaud, Jonathan Bastien Cottet

Microfluidic electrical impedance flow cytometry is now a well-known and established method for single-cell analysis. Given the richness of the information provided by impedance measurements, this non-invasive and label-free approach can be used in a wide ...

Dielectrophoresis‐assisted creation of cell aggregates under flow conditions using planar electrodes

Philippe Renaud, Harald Van Lintel, Jonathan Bastien Cottet, Soufian Lasli

We present a microfluidic platform allowing dielectrophoresis-assisted formation of cell aggregates of controlled size and composition under flow conditions. When specific ex- perimental conditions are met, negative dielectrophoresis allows efficient conce ...

MyDEP: A New Computational Tool for Dielectric Modeling of Particles and Cells

Philippe Renaud, Jonathan Bastien Cottet

Dielectrophoresis (DEP) and electrorotation (ROT) are two electrokinetic phenomena exploiting nonuniform electric fields to exert a force or torque on biological particles suspended in liquid media. They are widely used in lab-on-chip devices for the manip ...
