Characterizations of Cur-MnO2/HA NPs. A UV–vis absorbance spectra of HA, MnO2/HA NPs, free Cur, and Cur-MnO2/HA NPs. Inset: The appearance of each solution. B TEM image, C elemental mapping, D EDS analysis, E XPS spectrum, and F Mn 2p XPS spectrum of MnO2/HA NPs. G FT-IR spectra of HA, free Cur, and Cur-MnO2/HA NPs. The characteristic peaks of (1) 1281 cm−1 and (2) 1510 cm−1 of Cur can be ascribed to δ(CH) of C=CH and ν(C=O), respectively [35]. H Dynamic size of MnO2/HA NPs, free Cur, and Cur-MnO2/HA NPs. I Kinetics of H2O2 consumption and O2 generation catalyzed by MnO2/HA NPs. Radical scavenging activity of Cur-MnO2/HA NPs at different concentrations for J DPPH, K O2·−, and L ·OH
