Intravascularly-administrable, magnetically-localizable biodegradable carrier

摘要

The intravascularly-administrable, magnetically localizable biodegradable carrier comprises microspheres formed from an amino acid polymer matrix with magnetic particles embedded therein. The microspheres can be used for intraarterial 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.
