In vitro, the self-assembled P-4 nanoparticles can specifically target to lysosome subcellular site and realize protonated process of dibutaneaminophenyl(DBAP) groups with high photo toxicity. Under single 660 nm laser illumination, the tumor can be ablated completely with no side effects in vivo. This work demonstrates that the p H-responsive P-4 nanoparticles provide a new avenue for highly efficient cancer combination therapy.展开更多
