A Schematic illustration of the synthesis of MnAs@SiO2-pHLIPs and their functions in the tumor. After treating SMMC-7721 cancer cells with MnAs@SiO2 and MnAs@SiO2-pHLIP, the total amount of Mn ions (B) and As ions (C) in the cells at pH 7.4 and pH 6.0. F Flow cytometric analysis of SMMC-7721 cells incubated with different drugs for 2 h at different pH. SMMC-7721 cells served with free ATO, MnAs @ SiO2, and MnAs @ SiO2 pHLIP at pH 7.4. D And the cell viability at pH 6.0 (E) and pH 7.4. (n = 6) [40]
