The system contains spinach extract (SE), reduced graphene oxide (rGO) and gold nanocages (AuNCs). SE conduces to the formation of hydrogel, and also serves as a green material for improving the biocompatibility of hydrogel, and a natural pho- tosensitizer for killing tumor cells under laser radiation (fi60 nm). AuNts show obvious photothermy and can enhance the generation of cytotoxic singlet oxygen (102). The composite hydrogel shell on tumor cells exhibits several competitive advantages including enhanced antitumor effect by retaining the high con- centration of drugs around cancer cell, excellent PDT/FFr compatibility as well as high loading and controllable release of fluorouracil (5-FU) for synergetic multimodal treatment. The survival rate of HeLa cells incubated with 5-FU loaded hydrogel under NIR radiation for 10 min sharply decreases to 1.2%, in- dicating remarkably improved antitumor effects. These results demonstrate that the hydrogel is an excellent delivery carrier for localizable, NIR-responsive and combined PTT/PDT/Chemo synergetic antitumor.展开更多
