Title
(EN) INJECTABLE HYDROGELS AND USES THEREOF
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.
