Abstract

Using double emulsions combined with solgel chemistry, new multi-compartimented Wax/Water@SiO2 capsules have been synthesized, and are presented by Rénal Backov and co-workers. Their multi-compartmentalization allows the encapsulation of both hydrophilic and hydrophobic adjuvant, while a surrounding silica shell is offering confinement. The release of their contents is triggered by a thermal stimulus that swollen the wax through melting inducing thereby the rupture of the protecting silica shell.
