RONS scavenging selectively of Cr/CeO2 nanozyme. ROS scavenging abilities of the Cr/CeO2 nanozyme for A) OH and B) O2•- tested by ESR, respectively. C) Comparison of the ability of Cr/CeO2 nanozymes to scavenge free radicals for OH, O2•-, NO, ONOO- and DPPH. RNS scavenging abilities of the Cr/CeO2 nanozyme for D) NO, E) ONOO- and F) DPPH tested by ESR and UV-vis absorption spectra, respectively.
