Antioxidation performance and mechanism of Cu2O-Sr/Cur. a Schematic diagram of the generation of Cu(II)-Cur to improve antioxidation. b ESR spectra of the XO + X reaction system after various treatments. c O2•- inhibition rates of various treatments. d Inhibition rate of O2•- by Cu2O-Sr/Cur after reaction with H2O2 for different durations. e ESR spectra of the Fenton reaction system after various treatments. f MB degradation efficiency across treatment groups. g UV‒Vis absorption spectra of MB in a Fenton reaction system of Cu2O-Sr/Cur + H2O2 at different times. h Chemical mechanism of O2•- and •OH scavenging. Statistical significance among biologically independent samples (n = 3) was determined via ANOVA followed by Tukey’s multiple comparisons tests. The data are presented as the means ± SDs. Significant differences between groups are indicated as *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001, and ns: not significant
