Spinel ferrites have been extensively used for various biological applications including magnetic fluid hyperthermia, drug delivery and as contrast agents for magnetic resonance imaging (MRI). This paper investigates three of the most frequently used spinel ferrites, namely magnetite, cobalt ferrite and manganese ferrite. The study focuses on the comparison of the cytotoxic effects for three species. Structural analysis using X-ray diffraction is presented along with the cytotoxic effects on human fibroblast (WI38) cell line using the MTT essay.

Key words: Spinel ferrites, coprecipitation, magnetic nanoparticles, cytotoxicity
