A facile approach has been developed to synthesize Fe3O4@PAA(polyacrylic acid)nanoparticles(NPs)with carboxyl groups on the surfaces by polymerization with acrylic acid in Fe3O4 NPs aqueous suspension.Nitrilotriacetic acid(NTA)was conjugated to the magnetic NPs via well-known carboniimide chemistry using EDC and NHS.
