Notes:
PEG-modified ZnGd0.1Fe1.9O4 ferrite nanoparticles were synthesized by a coprecipitationprocess combined with a microemulsion technique. The effect of modification on the structure,magnetic properties of ZnGd0.1Fe1.9O4 nanoparticles was also investigated by XRD, FTIR, TEMand VSM. The results showed immobilizing PEG on the surfaces of magnetic nanoparticleseffectively improved their dispersibility. Magnetic measurements indicated that the as-preparedPEG-modified nanoparticles exhibited relatively high magnetic properties, although a slightreduction in saturation and remanent magnetization were observed compared with unmodifiedsamples. Therefore, with promising high magnetic behavior and potentially good biocompatibility,PEG-modified ZnGd0.1Fe1.9O4 ferrite nanoparticles would be feasible as thermoseeds for interstitialhyperthermia to tumor
