Abstract (en)
[origin: FR2753902A1] The invention concerns a particulate biodegradable matrix comprising: a biodegradable and hydrophilic core with a base of a carbohydrate or polyol or polyamine matrix, cross-linked and derived in the mass by variable amounts of ionic groups; a hydrophilic polymer layer, associated to the central core by chemical, for example ionic, interaction; surface molecules or polymers grafted on the external polymer layer by covalent bonds.
