Magnetite nanoparticles coated with chitosan and poly (acrylic acid) blends for biomedical applications

Abstract

In recent years, the synthesis and characterization of nanoparticles has been used in many are-as of science. Magnetite nanoparticles have been highly employed in many biomedical applications, such as drugs delivery system, catalysis, and magnetic resonance imaging. The properties of the magnetic materials depends on the stabilizer type, covering their surface. In this study was obtained magnetite nanoparticles with chitosan and poly (acrylic acid). Pure monomer of acrylic acid were subjected to photopolymerization, while a photopolymerization kinetics was followed by FTIR spectroscopy. The band corresponding to the C=C vibrations has been selected for calculation of conversion degree of monomer. The structure and mor-phology of the obtained nanoparticles characterized by ATR-FTIR spectroscopy, X-ray analy-sis, and transmission electron microscopy.
