Emulsions: Small 17/2009

Capsules with multiple compartments would enable encapsulation and storage of multiple types of cell and materials in a single capsule without risk of cross contamination. Additionally, nonspherical capsules would pack more densely than spherical counterparts to increase the storage efficiency. Here, nonspherical colloidosomes with multiple compartments are created using water-in-oil-in-water double emulsions as templates. Double emulsions with a controlled number of inner drops are generated using a glass capillary microfluidic device. The geometry of generated colloidosomes is controlled by varying the number of aqueous inner drops that are encapsulated in the oil phase.
