Once formed, microgel particles can be useful as scaffolds in the constructimi of other particles. A useful variant on the emulsification/ gelation approach to microfluidic synthesis of particles is the use of double emulsions in which it is possible to carefully adjust the size, monodispersity, and chemical composition within a microfluidic framework [3]. fri this case, microgel particles may form a stmctural scaffold to shift the relative position of the inner droplet in the emulsion and thus help to control the morphology of the particles subsequently produced.
