Abstract :
Magnetic particles i.e. Fe3O4 nanoparticles have received great attention because
of their potential biomedical applications like as MRI contrast agent, hyperthermia and
biosensing magnetic labels. For these biomedical applications, Fe3O4 nanoparticles particles
must have proper surface coatings and also acquire superparamagnetic properties with
relatively high Ms values. Here, we performed Gd doping of iron oxide particles and their in
situ surface modification through an electrochemical strategy. The prepared particles were
examined using XRD, IR, TG, FE-SEM and EDAX analyses and their covering with starch
and doping by Gd cations were approved. VSM data further proved the superparamagnetic
behavior of the electrosynthesized iron oxide particles.
