  • Method of making nanocomposites of metal oxide and reduced graphene oxide and use for cancer treatment
    Patent number: 10149862
    Abstract: A facile approach is described to prepare monodisperse Fe3O4 and Co3O4 nanoparticles 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 Co3O4 and Fe3O4 nanoparticles. UV/Vis study revealed the formation of Fe3O4/rGO and Co3O4/rGO nanocomposites with characteristics absorption maxima. Finally, preliminary results of using the Fe3O4/rGO and Co3O4/rGO composites for efficient killing of Human hepatocytes cancer (HepG2) cell are reported.
