Supplementary Figure 3: Standardization of the peroxidase-like activity of commercial Fe3O4 NPs.
From: Standardized assays for determining the catalytic activity and kinetics of peroxidase-like nanozymes
(a) The catalytic activity and (b) specific activity of commercial Fe3O4 NPs of two different sizes. The smaller NPs show higher catalytic activity under the same conditions. SA indicates specific activities. Error bars shown represent the standard error derived from three repeated measurements
