Evaluation of antibacterial activity and toxic metal removal of chemically synthesized magnetic iron oxide titanium coated nanoparticles and application in bacterial treatment.

Co-precipitation method was used for preparation of two types of iron oxide nanoparticles coated by titanium dioxide according to divalent salts used. The average size of iron oxide nanoparticles coated by titanium dioxide measured by particle size analyzer, ranged approximately between 20 nm and 100 nm with mean particle size of 60 nm. Characterization of the prepared nanoparticles was done by X-ray diffraction analysis and scanning electron microscope indicating the sole existence of inverse cubic spinel phase of magnetic iron oxide nanoparticles.
