**3.2 Emulsification-based methods**

There are different ways to obtain nanocapsules using nanoemulsions as a template, including emulsion-diffusion, emulsion-coacervation, and double emulsification. All of them involve the emulsification of the organic or the aqueous phase in the other using a low or high-energy homogenization technique, causing the surfactant

to self-assemble at the interface. The nature of the rest of the materials used in the continuous or in the dispersed phase will depend on the desired characteristics of the nanocapsules to be formulated.
