Abstract
Near-infrared (NIR)-light responsive graphene have been shown exciting effect on cancer photothermal ablation therapy. Herein, we report on the preparation of Fe3O4-decorated hollow graphene microspheres (rGO@Fe3O4) by a facile spray drying and coprecipitation method for the magnetically targeted and NIR-responsive chemo-photothermal combination therapy. The microspheres displayed very high specific surface area (~ 120.7 m2 g-1) and large pore volume (~ 1.012 cm3 g-1), demonstrating distinct advantages for a high loading capacity of DOX (~ 18.43%). NIR triggered photothermal effect of the rGO@Fe3O4 microspheres responded in an on-off manner and induced a high photothermal conversion efficiency. Moreover, The Fe3O4 on the microspheres exhibited an excellent tumor cells targeting ability. The chemo-photothermal treatment based on rGO@Fe3O4/DOX showed superior cytotoxicity towards Hela cells in vitro. Our studies indicated that rGO@Fe3O4/DOX microcapsules have great potential in combined chemo-photothermal cancer treatment.
