Schematics showing surface functionalization of the optimized MPI contrast agents for glioma targeting. (a) synthesis of the PMAO-PEG co-polymer, with active maleimide functional groups and (b) its assembly on the surface of the oleic acid coated nanoparticles after phase transfer to aqueous phases. (c) Thiolation of the lactoferrin molecules using Traut’s reagent and their conjugation to maleimide functionalized MPI contrast agents for in vivo brain cancer targeting experiments.
