Nanoparticles with SiO2 coating and cubic iron core show high saturation magnetization, excellent biocompatibility, and potential for MRI contrast agents.
Nanoparticles with SiO2 coating were synthesized to have a cubic iron core. These were found to have saturation magnetization very close to the highest possible value of any iron-containing nanoparticles and the bulk iron saturation magnetization. The in vitro toxicology studies show that they are highly biocompatible and possess better MRI contrast agent potential than iron oxide NPs.
