Poly(ethylene glycol) (PEG)/poly(ethylene imine) (PEI) modified superparamagnetic iron oxide nanoparticles (SPIONs) were synthesized by the thermal decomposition of iron (III) acetylacetonate (Fe(acac)₃) in PEG containing PEI. Transferrin (Tf) was employed to functionalize SPIONs. The potential of Tf-SPIONs as brain magnetic resonance (MR) imaging contrast agents was explored by using Kunming mice as an animal model. The in vivo experiments revealed that Tf-SPIONs exhibited an enhanced contrast time as compared with the PEG-SPIONs and PEG/PEI-SPIONs. Tf-SPIONs exhibit promising potential for bioimaging applications because of their advantages of dispersibility in water, low cytotoxicity and long circulation time in blood.
