A drop within a drop within a drop: A microfluidic technique is used to generate highly controlled multiple emulsions (see picture). The high degree of control and scalability afforded by this method makes it a flexible and promising route for engineering designer emulsions and microcapsules with multiphase structures. Moreover, its generality will enable fabrication of novel materials containing complex internal structures.
