Material consisting of at least a biodegradable polymer and cyclodextrins

摘要

The invention concerns a material consisting of at least a biodegradable polymer and a cyclic oligosaccharide, characterized in that at least one molecule of the oligosaccharide is grafted via a covalent bond to at least a molecule of the biodegradable polymer. The invention also concerns a method for preparing the material, the nanoparticles and microparticles derived from the material and uses thereof as biological vectors for active substances.
