| Abstract
| - We report a novel approach to continuous and scalable production of core−shell droplets andpolymer capsules in microfluidic devices. The described method is also useful in the synthesis of polymerparticles with nonspherical shapes. We used capillary instability-driven break-up of a liquid jet formed bytwo immiscible fluids. Precise control of emulsification of each liquid allowed for the production of highlymonodisperse core−shell droplets with a predetermined diameter of cores and thickness of shells. Wealso achieved control over the number of cores per droplet and the location of cores in the droplet. Wecarried out fast throughput photopolymerization of the monomeric shells and obtained polymer particleswith various shapes and morphologies, including spheres, truncated spheres and, hemispheres, and singleand multicore capsules.
