Abstract
Using metal oxide semiconductor nanomaterials for synergistic cancer treatment has recently attracted the attention of numerous researchers. Herein, oxygen-defective vanadium oxide nanodots (VO<sub>x</sub> NDs) with ultra-small size and great dispersibility were synthesized via a novel user-friendly method, and then doxorubicin was loaded onto the VO<sub>x</sub> NDs surfaces. The VO<sub>x</sub> NDs had great photothermal conversion efficiency and stability. Doxorubicin-loaded VO<sub>x</sub> NDs can simultaneously serve as therapeutic agent and tumor microenvironment-activable HSP60 inhibitor, resulting in improved efficacy of photothermal therapy and released active doxorubicin for chemotherapy. Finally, we show that synergistic treatment achieved significant therapeutic effects in mice. These results provided a promising strategy for developing novel methods of synthesizing metal oxide semiconductors for enhanced synergistic cancer treatment.
