Characterization of Ox-CS/Ce NPs and Ox-CS/CeRT NPs. Size distributions and TEM images of A Ox-CS/Ce NPs and B Ox-CS/CeRT NPs, scale bar = 100 nm. Yellow arrows indicate core-shell structure. C Zeta potentials of Ox-CS/Ce NPs and Ox-CS/CeRT NPs. D Hydrodynamic particle size changes of Ox-CS/CeRT NPs under different times of incubation with H2O2. E Characteristic diagram of the morphological change of Ox-CS/CeRT NPs cultivated with 500 µM H2O2, scale bar = 100 nm. Stability of Ox-CS/CeRT NPs at F 4 °C (PBS) and G 37 °C (PBS containing 10% FBS). H Drug release kinetics of RT, incubated with 0, 200, and 500 µM H2O2 in PBS. Data are shown as mean ± SD (n = 3)
