a TEM graphs (Scale bar, 100 nm), and hydrodynamic sizes of Cs-PBs synthesized with different methods. b Upper figure represents the specific activities of different Cs-PBs. Solid lines represent the linear fit of each specific activity, and the shaded areas denote the 95% confidence band. Lower figure refers corresponding hydroxyl radical generation capacity. c The degradation curves of MB and d the calculated kobs according to the pseudo-first-order kinetics in a series of iron-based catalytic systems (Conditions: [MB]0 = 0.2 mg/L, [H2O2]0 = 500 mM, [Catalyst] = 2 mg/L, pH = 4.0). e MALDI-TOF-MS results of MB degradation in different iron-based catalytic systems. f Cyclic catalysis results of CsPB-1 towards MB degradation in ambient temperature. g Cell viability of 4T1 and 3T3 cells treated with CsPB-1 for 24 h. The curves represent a nonlinear fit based on the dose-response function. h Laser scanning confocal microscopy images of ROS levels for 4T1 cells treated with PB-0 and CsPB-1 (Scale bar, 20 μm). PBS-treated 4T1 cells were used as control. i Quantitative results of mean fluorescence intensity for ROS levels of 4T1 and 3T3 cells. Error bars in b, c, f, g indicate the standard deviation of three independent experiments, and bars in i denote four independent experiments.
