Confined emulsification
Emulsions are a very common material encountered in everyday life and in various industrial applications, from the food and cosmetic industries to biotechnologies. The development of microfabrication techniques has offered the possibility of finely controlling liquid flows and thus producing calibrated emulsions. Various emulsification processes have been proposed along with increasing production capacities by parallelizing droplet makers. However, it is challenging to mass produce droplets in the size range of 1 to 10 micrometres, a size that is of particular interest for creating microparticles used in life science applications or as emulsion models for investigating their stability or rheological properties.
I will introduce a strategy to push forward this limitation by discussing its own limitation mainly related to the transport and the availability of surfactants required for the stabilization of the emulsion against coalescence.
