Yu, Ji-HunLee, Jai-SungChoa, Yong-HoHofmann, Heinrich2011-12-212011-12-212011-12-21201010.1016/S1005-0302(10)60054-0https://infoscience.epfl.ch/handle/20.500.14299/75911SiO2 coated γ-Fe2O3 nanocomposite powder has been successfully synthesized by chemical vapor condensation process and its feasibility on hyperthermic application was investigated in this study. The power loss of SiO2 coated γ-Fe2O3 nanocomposite powder which means the magnetic heating effect under alternative magnetic field was much higher than the single phase γ-Fe2O3 nano powder due to the very fine size under 20 nm and well dispersion in biologically compatible SiO2 matrix. The superparamagnetism and hyperthermic property of SiO2 coated γ-Fe2O3 nanocomposite powder were discussed in terms of microstructural development in this study.HyperthermiaNano-BioChemical vapor condensationSilica coated iron oxide nanoparticleSuperparamagnetismParticlestext::journal::journal article::research article
