Abstract

The present invention relates to the field of polymer chemistry and more particularly to encapsulated contrast agents and methods for using the same. One embodiment of the present invention provides a micelle having a contrast agent encapsulated therein, comprising a multiblock copolymer which comprises a polymeric hydrophilic block, optionally a poly(amino acid block) that is optionally crosslinkable or crosslinked, and another poly(amino acid) block, characterized in that said micelle has an inner core, optionally a crosslinkable or crosslinked outer core, and a hydrophilic shell.
