The end hydroxyls of triblock copolymer Pluronic F127 have been modified to amino-groups by a series of reactions. Using the macromonomer aminating F127, the bioactive macromolecular folic acids which are as the targeting ligand have been conjugated to the end group of F127. 1H-NMR and FT-IR were adopted to characterize the structures of copolymers Amphiphilic F127-Folate self-assembled into micelles by dialysis method. The morphologies of the aggregates were investigated by TEM. The results proved that F127-Folate can self-assemble into nanomicelles in water.
