Synchronous chemotherapy and radiotherapy,termed chemoradiation therapy,is now an important standard regime for synergistic cancer *** such treatment,nanoparticles can serve as improved carriers of chemotherapeutics into tumors and as better radiosensitizers for localized ***,we designed a Schottky-type theranostic heterostructure,bi_(2)S_(3)-Au,with deep level defects(DLDs)in bi_(2)S_(3) as a nano-radiosensitizer and CT imaging contrast agent which can generate reactive free radicals to initiate DNA damage within tumor cells under X-ray ***(MTX)was conjugated onto the bi_(2)S_(3)-Au nanoparticles as a chemotherapeutic agent showing enzymatic stimuli-responsive release *** designed hybrid system also contained curcumin(CUR),which cannot only serve as a nutritional supplement for chemotherapy,but also can play an important role in the radioprotection of normal ***,this combined one-dose chemoradiation therapeutic injection of co-drug loaded bimetallic multifunctional theranostic nanoparticles with a one-time clinical X-ray irradiation,completely eradicated tumors in mice after approximately 20 days after irradiation showing extremely effective anticancer efficacy which should be further studied for numerous anti-cancer applications.
