Abstract

original image

Nonspherical colloidosomes with multiple compartments are generated using water-in-oil-in-water double emulsions with controlled morphology as templates (see image). Double emulsions are prepared using a glass capillary microfluidic device that provides a precise means to control the number of internal aqueous droplets and the volume ratio of oil and aqueous phases.
