Abstract

We present Au@Fe₃O₄ nanoparticles obtained from Fe nanoparticles and HAuCl₄ using a simple solvothermal method. Trisodium citrate (C₆H₅Na₃O₇*2H₂O) served as a reducing agent for Au. X-ray diffraction analysis, electronic microscopes and energy-dispersive X-ray spectroscopy revealed cubic structure, elemental composition (Au, Fe and O) and spherical shape of nanoparticles. Antibacterial activity of the sample was tested against E. coli bacteria and obtained results were discussed.
