This system can be emulsified and leads to droplets of submicron size. Monolinolein has a rich polymorphism with water and exhibits cubic and hexagonal phases. Among the phases that can be emulsified are those occurring in excess of water. It has been shown that the addition of a third component such as oil can modulate the internal structure (see Fig. 1) [19]. Moreover, an additional micellar cubic phase can be emulsified leading to the so-called micellar cubosomes [20]. We would like to benefit from the internal structure already present in these emulsified soft particles by polymerizing the oil phase. This promising simple synthesis of porous PS nanoparticles does not need any costly removal of the templates or any further lost of energy. A second objective of this work was to vary the liquid crystalline phase into the droplets [19,21,22] in order to control the porosity type of polymerized nanoparticles.
