- Abstract
- The modulation of intracellular reactive oxygen species (ROS) levels is crucial for cellular homeostasis and determination of cellular fate. A sublethal level of ROS sustains cell proliferation, differentiation and promotes tumor metastasis, while a drastic ROS burst directly induces apoptosis. Herein, surface-oxidized arsenene nanosheets (As/AsxOy NSs) with type II heterojunction are fabricated with efficient .O-2(-) and O-1(2) production and glutathione consumption through prolonging the lifetime of photo-excited electron-hole pairs. Moreover, the portion of AsxOy with oxygen vacancies not only catalyzes a Fenton-like reaction, generating .OH and O-2 from H2O2, but also inactivates main anti-oxidants to cut off the "retreat routes" of ROS. After polydopamine (PDA) and cancer cell membrane (M) coating, the engineered As/AsxOy@PDA@M NSs serve as an intelligent theranostic platform with active tumor targeting and long-term blood circulation. Given its narrow-band-gap-enabled in vivo fluorescence imaging properties, As/AsxOy@PDA@M NSs could be applied as an imaging-guided non-invasive and real-time nanomedicine for cancer therapy. Multifunctional materials with a number of effects are important for dealing with the complex environment in cancer therapy. Here, the authors report on surface-oxidized arsenene nanosheets coated with polydopamine and cancer cell membrane as a multi theranostic tumour targeting cancer therapy.
