Abstract
A facile approach is described to prepare monodisperse FeOand CoOnanoparticles on chemically reduced graphene oxide (rGO) to form nanocomposites by low temperature solution route and MWI method, respectively. These processes are environmentally friendly and convenient compared with previously reported methods. The synthesized nanocomposites were characterized using x-ray diffraction spectroscopy (XRD), raman spectroscopy, scanning electron microscopy (SEM) measurements and UV/Vis absorption spectroscopy. XRD patterns revealed the high crystalline quality of the nanocomposites. SEM micrographs showed the morphology of the rGO nanosheets decorated by CoOand FeOnanoparticles. UV/Vis study revealed the formation of FeO/rGO and CoO/rGO nanocomposites with characteristics absorption maxima. Finally, preliminary results of using the FeO/rGO and CoO/rGO composites for efficient killing of Human hepatocytes cancer (HepG) cell are reported. Nanocomposites produced by MWI showed better anticancer activity and higher yield than that of low temperature solution route.
