Multifunctional MoS2 nanosheets with Au NPs grown in situ for synergistic chemo-photothermal therapy.

| Abstract |
The treatment of cancer has always been a worldwide problem. The combination of chemotherapy and other therapies would be a promising therapy strategy. Photothermal therapy (PTT) does not cause serious side effects and has dual control of time and space, which was considered to be a good method for combination with chemotherapy. Here, we modified multifunctional nanosheets based on in-situ gold nanoparticles (Au NPs) grown molybdenum disulfide (MoS2) to combine their excellent photothermal conversion and drug loading capabilities. More importantly, the target peptide cRGD modified nanosheets have good selectivity to tumor cells rich in integrin receptors, and drug loading and drug release tests showed that it could carry enough chemotherapeutic drugs and had excellent photo controlled release performance. In vitro cell experiments showed that the drug-loaded multifunctional nanosheets had good anti-tumor effect under 808 nm laser irradiation. Therefore, the multifunctional nanosheets designed in this paper have great potential in the study of targeted drug release and chemo-photothermal therapy combined therapy, and are of great significance for in vivo and clinical research.
