Although recent advances have been made in improving the efficacy of photodynamic therapy, efficient therapeutic approaches based on reactive oxygen species (ROS) are needed, particularly mitochondria-specific targeting of nanomaterials that can alter the internal environment of organelles. Herein, we report the facile synthesis of mitochondria-specific anchored nano-complexes (AG-C-NP) comprised of a skeleton of gold and carbon atoms for cancer therapy. Compared to the effects of gold nanoclusters (Au NCs), AG-C-NP showed enhanced fluorescence imaging effects, which can be used for tumor monitoring. AG-C-NP targeted the mitochondria and increased ROS damage in cancer cells. After treatment with AG-C-NP, the tumor inhibition rate reached 70.94%, which was 25.98% and 36.91% higher than that of free doxorubicin (DOX) and gemcitabine (Gem), respectively. Studying the mechanism of AG-C-NP inhibiting cancer shows that AG-C-NP could promote tumor cells to produce excessive ROS by overexpressing P53 and increasing the number of apoptotic cancer cells, which was caused by overexpression of Caspase1 that was closely related to cell apoptosis. AG-C-NP is a promising anticancer drug that targets the mitochondria in vivo to trigger excessive ROS production in tumor cells and inhibit tumor growth.
