Characterization and antioxidant properties of Ag14 clusterzymes. a Schematic illustration of Ag14 clusterzymes. b Optical absorption (purple line) and photoemission (blue line, λex = 480 nm) spectra of Ag14 clusterzymes. Insets: photographs of Ag14 clusterzymes and the red-emitting Ag14 clusterzymes taken under visible and UV light. c Typical TEM image of Ag14 clusterzymes. Insets: size distribution of Ag14 clusterzymes obtained from TEM image. d •OH clearance ability of Ag14 clusterzymes under different concentrations characterized by SA assays. e The SOD-like activity of Ag14 clusterzymes at different concentrations characterized by WST-8 and the comparison with natural SOD. f Time-dependent total antioxidant capacity of Ag14 clusterzymes under different concentrations characterized by ABTS assays
