Two dimensional magnetic manipulation of microdroplets on a chip

Martinus Gijs, Virendra Kumar Parashar, Ulrike Lehmann

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 ...

Contactless electrochemical actuator for precise sampling on microchip

Martinus Gijs, Lynda Metref, Daniel Berdat

The scope of this work has been the design of a mechanical actuator in polydimethylsiloxane (PDMS) / glass for precise liquid sampling, based on the electrochemical generation of O2. The device is composed of two chambers separated by a PDMS membrane. In t ...

Accurate masking technology for high-resolution powder blasting

Abdeljalil Sayah, Martinus Gijs, Anne-Gabrielle Pawlowski

We have combined eroding 10 µm diameter Al2O3 particles with a new masking technology to realize the smallest and most accurate possible structures by powder blasting. Our masking technology is based on the sequential combination of two polymers:(i) the br ...

Glass valveless micropump using electromagnetic actuation

Christophe Yamahata, Martinus Gijs, Frédéric Lacharme

We present a valveless micropump in glass, which is magnetically actuated using the sinusoidal current of an external electromagnet. We employ a powder blasting microerosion process for microstructuring the glass substrates and fusion bonding for assembly ...

Electromagnetically Actuated Ball Valve Micropumps

Christophe Yamahata, Martinus Gijs, Frédéric Lacharme

We present two types of oscillating diaphragm micropumps configured with passive ball valves and using electromagnetic actuation. One type is made out of poly(methyl methacrylate) (PMMA), while the other one is made out of borosilicate glass. Both were pro ...
