Fluorinated graphene (FG) inherits the excellent performance of graphene and fluorinated carbon, and has many outstanding properties in biological fields. However, the hydrophobic nature and harsh preparation conditions greatly limit its further functionalization and practical applications. Herein, a novel strategy is reported to prepare water-soluble fluorinated graphene oxide (FGO), and this method also facilitates us for the first time to decorate FGO with magnetic Fe3O4 nanoparticles. The constructed novel (FGO/Fe3O4) nanocomposite not only shows good biocompatibility even at high concentration, but exhibits excellent photothermal efficiency in near infrared region. Moreover, the improved dispersibility and high surface area also enable the nanocomposite to have drug loading capacity, and cell experiment study indicates the nanocomposite is a valuable candidate for cancer photo-chemotherapy.
