▎ 摘　　要

Partially reduced grphene oxides (pRGO(1)-pRGO(3),pRGO(1-3))were synthesized using a mild reduction method by incubating GO suspension under alkaline condition at room tempeature. Structure and morphology of the as-synthesized pRGO(1-3) nanocomposites were confirmed by means of FTIR,Raman,XPS,UV-Vis,transmission electron microscopy (TEM)and energy dispersive spectrometer (EDS). pRGO possesses synergistic photodynamic and photothermal effects on tumor cell upon near-infrared (NIR)light irradiation. Consequently,pRGO can be expected to be a new nano carrier for tumor photodynamic and photothermal therapy.
