Abstract: Photoactivated therapy is an exciting new method of cancer treatment. A new light-stimulus dual-drug responsive nanoparticles based on mesoporous silica nanoparticles(MSN) were developed to control cellular anticancer drug release. The prepared Curcumin(Cur)-loaded nanoparticles MSN-Pt-PEG@Cur[PEG=poly(ethylene glycol)] could be activated by photostimulation to generate reactive oxygen species(ROS) from Cur and Pt(Ⅱ) from Pt(IV), respectively. Compared with free anti-cancer drugs' chemotherapy and single photoactivated therapy, the prepared MSN-Pt-PEG@Cur displayed increased cytotoxicity. Therefore, the strategy of light-stimulus dual-drug responsive nanoparticles is a promising approach to photoactivated therapy.
