A novel sandwich-like nanocomposites of rGO/Fe₃O₄@mSiO₂ were successfully fabricated through a facile method. The morphology and properties of nanocomposites were characterized by SEM, TEM, FTIR, XRD and N₂ adsorption-desorption. As a result, it was observed that the nanocomposites exhibit the saturation magnetization of 32 emu·g^-1, and possess abundant pores with a large surface area as much as 217 m²·g^-1. The loading capacity of Pentafluorouracil (5-FU) with the nanocomposites was high(57.34%). The formation mechanism of rGO/Fe₃O₄@mSiO₂ was discussed. Additionally, the synergistic anticancer efficacy of as-prepared nanocomposites against HeLa cell line was investigated by MTT assay and cell fluorescence microscopic imaging analysis. The results indicated that 5-FU loaded in the nanocoposites is effectively delivered to tumor lesion sites under the action of magnetic targeting. Moreover, the rGO/Fe₃O₄@mSiO₂ nanocomposites have excellent photothermal conversion properties under light conditions, and show significant killing effect on HeLa cells.
