Surface-oxidized arsenene nanosheets (As/AsxOy NSs) with type II heterojunction were fabricated by ball-grinding and liquid exfoliation. After polydopamine (PDA) and cancer cell membrane (M) coating, the engineered As/AsxOy@PDA@M NSs serve as an intelligent theranostic platform with photothermal (PT) and fluorescence imagings guided photothermal therapy (PTT), photodynamic therapy (PDT), chemodynamic therapy (CDT), and inactivate antioxidant enzymes (AOEs).
