摘要:
The intravascularly-administrable, magnetically- localizable biodegradable carrier comprises microspheres (A) formed from an amino acid polymer matrix (C) with magnetic particles (P) embedded therein. The microspheres can be used for intra-arterial administration and capillary level localization and/or release of therapeutic and diagnostic agents, thereby obtaining much more precise targeting of the agents than has heretofore been possible.
