Characterization of OA-CNPs and PEG-CNPs. a TEM image of OA-CNPs. Inset, high-resolution TEM image of OA-CNPs. b TEM image and dynamic light scattering analysis (inset) of PEG-CNPs. c XPS spectrum of PEG-CNPs identifies the state of valence and binding energy peaks for Ce3+ (peaks at 884.5, 900.8 and 903.1 eV) and Ce4+ (peaks at 881.7, 888.5, 897.5, 906.7 and 916.2 eV). d The superoxide-mimicking ability of PEG-CNPs. e The catalase-mimicking ability of PEG-CNPs. f The hydroxyl radical eliminating capacity of PEG-CNPs. Data represent means ± s.d. n = 3. *P < 0.05, **P < 0.01, ***P < 0.001
