Microfluidic Mass-Transfer Control for the Simple Formation of Complex Multiple Emulsions

摘要

Multiple emulsions have complex internal structure in which the droplets of the dispersed phase themselves contain even smaller dispersed droplets. They have significant potential in many applications, including pharmaceutics, foods. cosmetics, microspheres, microcapsules, and chemical separations. Double emulsions are typically formed through a two-step bulk emulsification process. Owing to hydrodynamic heterogeneity in large-scale equipment, it is difficult to prepare multiple emulsions with a narrow droplet size distribution and precise microstructure.
