MAGHEMITE NANOPARTICLES AND METHOD FOR PREPARING THEREOF

摘要

The present application relates to a method for preparing stoichiometrically pure maghemite iron superparamagnetic nanoparticles. The method for preparing maghemite (gamma-Fe2O3) superparamagnetic nanoparticles disclosed in the present application is characterized by a step of reduction and appropriate steps of oxidation of the Fe-based composition obtained by the same. The maghemite nanoparticles obtained show a suitable size as well as binding properties without any surface modification. These nanoparticles can be therefore easily used as reagents for detection of inorganic and/or organic molecules as well as nanocarriers of organic and/or biomolecules.
