Chemically homogeneous microparticles for controlled delivery of biologically active molecules are described, said microparticles being made up of a core comprising a component which is essentially of proteic nature and a natural, synthetic or semisynthetic polymer, and of an outside layer consisting of natural, synthetic or semisynthetic molecules that can be recognized by receptors or components of cell surface of living beings, or that can recognize natural, synthetic or semisynthetic molecular structures. |
