  • Material based on biodegradable polymers and method for preparing same
    Publication number: 20040013626
    Abstract: A material with controlled chemical structure includes at least a biodegradable polymer material and a polysaccharide with linear, branched or crosslinked skeleton. The material is obtained by controlled functionalizing of at least a molecule of the biodegradable polymer or one of its derivatives by covalent grafting directly at its polymeric structure, of at least a molecule of the polysaccharide. A vector preferably in the form of particles obtained from the material and its use as biological vector are also disclosed.
