Abstract

In recent decades, there has been considerable interest in magnetic nanoparticles study field, which is an applicable, high, productive, effective since it can be utilized as an agent for the wide bio, experimental, scientific and industrial applications. As the wide range of application ofsuperparamagnetism nano Fe3 O4, especially in bio fields, Magnetite and Functionalized magnetic nanoparticles composed of Fe3 O4 particles stabilised by Silane derivations prepared by the co-precipitation method. For characterization of core-shell crystallographic structure of synthesized magnetic nanoparticles, X-ray diffractometer used. Produced MNPs morphology andtheir size distribution observed by scanning electron microscopy. In order to confirm the modification of magnetite surface with Alkyl Silane some physical techniques, including Fourier transform infrared spectroscopy, element analysis (CHNS), and for magnetic measurement of magnetic nanoparticles (MNPs), Vibrating Sample Magnetometer, and finally for measurement of MNPs surface’ s zeta potential and hydrodynamic diameter, zetasizer and Dynamic light Scattering used respectively. Results of referred techniques indicated that all the core-shell MNPs synthesized successfully and major step of functionalization of MNPs well have done.
