Abstract

Macromolecole ramificate di tipo dendrimerico, costituite da un nucleo centrale (preferibilmente neopentilico) e da una serie di catene poliossialchileniche propagantisi da detto nucleo con ramificazioni a cascata, si prestano come trasportatori di farmaci o agenti di contrasto, veicolanti di specie metalliche radioattive, eccetera.
