Automated microfluidic sorting of mammalian cells labeled with magnetic microparticles for those that efficiently express and secrete a protein of interest

Amar Rida, Nicolas Mermod, Etienne Lançon, Niamh Harraghy

We developed a method for the fast sorting and selection of mammalian cells expressing and secreting a protein at high levels. This procedure relies on cell capture using an automated microfluidic device handling antibody-coupled magnetic microparticles an ...

Dispositif de manipulation et de transport de perles magnetiques

Martinus Gijs, Amar Rida

A device for transporting magnetic or magnetisable microbeads ( 25 ) in a capillary chamber ( 14 ) comprises a permanent magnet ( 10 ) or an electromagnet ( 11 ) for subjecting the capillary chamber to a substantially uniform magnetic field, to apply a per ...

Friction based locomotion module for mobile MEMS robots

Reymond Clavel, Jean-Marc Breguet, Amar Rida, Walter Driesen

The “Modulated Friction Inertial Drive (MFID) principle” is presented as a locomotion solution for mmsize micro robots dealing with both size constraints and limitations in terms of power consumption. Based on one of the configurations of this locomotion p ...

Two-dimensional magnetic manipulation of microdroplets on a chip as a platform for bioanalytical applications

Martinus Gijs, Ulrike Lehmann, Amar Rida, Virendra Kumar Parashar, Caroline Vandevyver

Manipulating biological samples in microliter droplets has vast potential in molecular diagnostics. We present a system for the two-dimensional (2D) magnetic manipulation of aqueous droplets suspended in silicone oil as a platform for on-chip bioanalysis. ...

Two dimensional magnetic manipulation of microdroplets on a chip

Martinus Gijs, Ulrike Lehmann, Amar Rida, Virendra Kumar Parashar

In this paper we describe the two-dimensional (2D) magnetic manipulation of aqueous droplets suspended in silicone oil over the chip surface. The magnetic actuation is based on the force imposed on superparamagnetic microparticles inside the droplets. Thes ...
