Abstract
(EN)
The invention relates to a hydrogel, in particular degradable or non degradable, comprising monomers of formula (I) and organosilica particles or porous silicon particles covalently bound thereto, optionally with non covalently bound organosilica and/or silicon particles mixed therewith, in particular degradable organosilica nanoparticles or core-shell nanocapsules; pharmaceutical, veterinary or cosmetic compositions thereof; and uses thereof as a medicament. The present invention finds applications in the therapeutic and diagnostic medical technical fields and also in cosmetic and veterinary technical fields.
(FR)
L'invention concerne un hydrogel, en particulier dégradable ou non dégradable, comprenant des monomères de formule (I) et des particules organosiliciques ou des particules poreuses de silicium liées par covalence à ceux-ci, éventuellement avec des particules organosiliciques et/ou de silicium liées de manière non covalente, mélangées à celles-ci, en particulier des nanoparticules organosiliciques dégradables ou des nanocapsules de type noyau-coquille dégradables ; des compositions pharmaceutiques, vétérinaires ou cosmétiques correspondantes ; et des utilisations correspondantes en tant que médicament. La présente invention trouve des applications dans les domaines techniques médicaux thérapeutiques et diagnostiques ainsi que dans les domaines techniques cosmétiques et vétérinaires.
