Drug Delivery with PEGylated MoS2 Nano-sheets for Combined Photothermal and Chemotherapy of Cancer

MoS2 nanosheets functionalized with poly ethylene glycol are for the first time used as a multifunctional drug delivery system with high drug loading capacities. Using doxorubicin as the model drug and taking advantages of the strong near-infrared absorbance of MoS2, combined photothermal and chemotherapy of cancer is realized in animal experiments, achieving excellent synergistic anti-tumor effect upon systemic administration.
