Speaking of the Industry world and Research, Pierre-Gilles de Gennes used to say that « both have everything to gain by working together ». Regarding the frontiers between scientific domains, he stressed that we should be able to overcome them in order to make each scientific domain more successful and fully exploit their potentials. Pierre-Gilles de Gennes Institute – IPGG – has been created along these lines of thought: its goal is to bring together, in a cross-disciplinary domain (microfluidics), experts from various disciplines (physics, biology, chemistry, technology), and develop both fundamental and applied research. Industrial domains interested by microfluidics are numerous (food industry, medicinal field, cosmetics, oil industry, instrumentation, ...).
