COPOLYMERS COMPRISING POSITIVELY AND NEGATIVELY CHARGED AMINOACIDS CONJUGATED TO CHELANTS

摘要

A polymer is conjugated to a plurality of molecules having at least a functionality and further comprises an active agent, such as a diagnostic agent or a therapeutic agent. The diagnostic agent is capable of generating a signal detectable by a medical imaging technique. The conjugated polymer has an extended conformation and provides enhanced contrast of images of diseased tissues or enhanced delivery of therapeutic agents to these tissues.
