CA 2622196

The invention relates to the filling of hydrophobic or hydrophobically modified porous microparticles with hydrophobic substances and to the subsequent encapsulation of the resultant hydrophobic particles using layer-by- layer (LbL) polyelectrolyte technology in order to produce homogeneous suspensions in water and to enable the controlled release of the encapsulated active ingredients. Adhesion to the target site is improved by a specific modification of the LbL surface.

L'invention concerne un procédé consistant à remplir des microparticules poreuses hydrophobes, ou modifiées hydrophobiquement, avec des substances hydrophobes, puis à encapsuler les particules hydrophobes ainsi produites par la technologie de dépôt "couche par couche" (LbL, de l'anglais "Layer-by-Layer") de polyélectrolytes afin de produire des suspensions homogènes dans l'eau et d'obtenir une libération contrôlée des principes actifs encapsulés. Une modification spécifique de la surface LbL permet d'obtenir une adhérence privilégiée sur le site cible.
