The invention relates to particles comprising a core based on at least one biodegradable organo-soluble polymer. The inventive particles are characterised in that at least part of the surface thereof is coated with at least one hyaluronan or one of the derivatives thereof, said hyaluronan being a water-soluble, amphiphilic hyaluronan of which the carboxylic functions are in part transformed in order to form hydrophobic groups. |
