Abstract
In this paper, the magnetic graphene oxide (Fe3O4@GO) has been successfully prepared by decomposition of Iron (III) acetylacetonate in the mixture solution of triethylene glycol and GO. atomic force microscope, TEM, XRD and superconducting quantum interference device were used to characterize the material. The results showed that the magnetic Fe3O4 nanoparticles modified graphene oxide has been obtained, and it has superparamagnetism with magnetization saturation of 16.4emu/g. the Fe3O4@GO has a good sustained-release performance, and vitro cytotoxicity confirmed that its security for Fe3O4@ GO as a potential drug carrier.
