Laser microfluidics: fluid actuation by light (2009)
Delville, Jean-Pierre, Schroll, Robert D., Chraibi, Hamza, Issenmann, B., Wunenburger, Régis, ...
The development of microfluidic devices is still hindered by the lack of robust fundamental building blocks that constitute any fluidic system. An attractive approach is optical actuation because...
Stretching and squeezing of sessile dielectric drops by the optical radiation pressure (2009)
Chraibi, Hamza, Lasseux, Didier, Arquis, Eric, Wunenburger, Régis, Delville, Jean-Pierre
We study numerically the deformation of sessile dielectric drops immersed in a second fluid when submitted to the optical radiation pressure of a continuous Gaussian laser wave. Both drop stretching...
Simulation of an optically induced asymmetric deformation of a liquid-liquid interface (2009)
Chraibi, Hamza, Lasseux, Didier, Arquis, Eric, Wunenburger, Régis, Delville, Jean-Pierre
Deformations of liquid interfaces by the optical radiation pressure of a focused laser wave were generally expected to display similar behavior, whatever the direction of propagation of the incident...

Laser Switching and Sorting for High Speed Digital Microfluidics (2008)
Wunenburger, Régis, Delville, Jean-Pierre
We used thermocapillary stresses induced locally by laser on flowing drops to build high throughput drop switchers and sorters for digital microfluidics. Since the laser is disconnected to the chip,...

ISSENMANN , Bruno, Régis Wunenburger, Sébastien Manneville, Jean-Pierre Delville
En focalisant une onde acoustique sur l'interface entre deux fluides, on déforme cette interface par pression de radiation. Si l'interface est totalement transparente, la déformation de l'interface...
Contrôle tout-optique du cycle de la vie d'une gouttelette en microcanal (2007)
François Gallaire, Régis Wunenburger, Charles Baroud, Jean-Pierre Delville
La formation et le transport d'une gouttelette dans un microcanal sont généralement imposés par la géométrie figée de ce microcanal. Pour surmonter cette contrainte, nous présentons une...
Simulation numérique de l'hydrodynamique d'interfaces liquide-liquide contrôlées par laser (2007)
CHRAIBI , Hamza, Didier Lasseux, Eric Arquis, Régis Wunenburger, Jean-Pierre Delville
Le contrôle de la déformation sans contact des interfaces liquides à l'échelle micro-métrique est un enjeu majeur pour toute une série d'applications en micro-fluidique. Une technique originale...
Liquid Transport Due to Light Scattering (2007)
Schroll, Robert D., Wunenburger, Régis, Casner, Alexis, Zhang, Wendy W., Delville, Jean-Pierre
Using experiments and theory, we show that light scattering by inhomogeneities in the index of refraction of a fluid can drive a large-scale flow. The experiment uses a near-critical, phase-separated...
Thermocapillary valve for droplet production and sorting (2007)
Baroud, Charles, Delville, Jean-Pierre, Gallaire, François, Wunenburger, Régis
Droplets are natural candidates for use as microfluidic reactors, if active control of their formation and transport can be achieved. We show here that localized heating from a laser can block the...
