Surface Modification ofMagneticIronOxideNanoparticles

Functionalizedironoxidenanoparticles(IONPs) are of great interest due to wide range applications, especially in nanomedicine. However, they face challenges preventing their further applications such as rapid agglomeration, oxidation, etc. Appropriate surface modification of IONPs can conquer these barriers with improved physicochemical properties.
