Superparamagnetic iron oxide nanoparticles coated with a folate-conjugated polymer

Quan Zhang、Chenhong Wang、Lei Qiao 等 5 位作者2009-01-01Journal of Materials Chemistry

Folate-functionalized magnetic fluids were prepared by direct chemisorption of a folate-tetra(ethylene glycol)-poly(glycerol monoacrylate) (FA-TEG-PGA) conjugate on Fe3O4nanoparticles. In the magnetic fluids, the PGA block of FA-TEG-PGA was chemisorbed onto the Fe3O4nanoparticle surface through its 1,2-diol groups, wh…
