Ethylenediaminetetraacetic Acid and Polyvinyl Chloride Grafted Zinc Cations doped Magnetite Nanoparticles for Biomedical Applications: Electrochemical Synthesis and Characterization

In this paper, two-types of superparamagnetic metal-ions doped iron oxide nanoparticles including ethylenediaminetetraacetic acid-grafted Zn2+ doped SPIONs (EDTA-Zn-SPIONs) and polyvinyl chloride-grafted Zn2+ doped SPIONs (PVC-Zn-SPIONs) nanoparticles are reported. These nanoparticles are fabricated through base generation cathodic electrodeposition method. The surface coat onto the prepared particles and zinc-doping into iron oxide were proved though Fourier-transform infrared spectroscopy, Field-emission scanning electron microscopy and Energy Dispersive X-ray analyses. The magnetic data was provided by sample vibrating magnetometer (VSM) technique. The EDTA-Zn-SPIONs exhibited magnetic performances of Ms=34.12 emu/g, Hci= 9.1G, Mr=0.29 emu/g, Mr(+)=+0.21 emu/g, Mr(-)=-0.38 emu/g Hci(+)=11.28G and Hci(-)=-6.75 G. Also, PVC-Zn-SPIONs showed Ms=28.45 emu/g, Hci=5.75G, Mr=0.14 emu/g, Mr(+)=-0.11 emu/g, Mr(-)=-0.18 emu/g, Hci(+)=7.75G and Hci(-)=3.75G. These data confirmed the quality of both prepared particles for biomedical applications.
