Droplet based Microfluidics
Jeudi 7 février 2013 13:00
- Duree : 1 heure
Lieu : Amphithéâtre M001 - Ecole PHELMA Minatec - Parvis Louis Néel - 38000 Grenoble
Orateur : Vincent SENEZ (IEMN, Villeneuve d'Ascq)
After a short introduction about wettability of homogenous and heterogenous surfaces, we will show how roughness at microscale can give ‘super’-wetting prope rties (superomniphobic surfaces) to these surfaces. We will explain how we have fabricated such surfaces using either semiconductor or polymer surfaces. Finally, we will explore several of their features, namely their static wetting, the adhesion of liquids on these surfaces and their robustness. The second part of the talk is dedicated to the use of these surfaces in various applications using lab-on-a-chip technology. We will introduce several approaches to move droplets on surfaces using electrowetting, photowetting and surface acoustic wave. We will show how to optimize these technologies to make them robust and reduce the energy consumption. Finally, we will present several applications coupling electrowetting and biosensing.
