Iron(II, III) oxide magnetic nanoparticles (NPs) have been coated with (3-Chloropropyl) trimethoxysilane and subsequently functionalized with 4-Amino-2,2,6,6-tetramethylpiperidine-N-oxyl and Amoxicillin. Finally, the functionalized iron oxide NPs have been coated with natural polymer, chitosan, in order to prevent NPs agglomeration in aqueous environment. The product was characterized by Fourier transform infrared (FTIR) spectroscopy and transmission electron microscopy (TEM). It was studied by the electron paramagnetic resonance method and the parameters describing the magnetic properties of the investigated nanoparticles, such as g-factor and line width, were calculated. © 2014 Elsevier Ltd.
