Supplementary Figure 2: Size-dependent peroxidase-like activity of Fe3O4 nanozymes.
From: Standardized assays for determining the catalytic activity and kinetics of peroxidase-like nanozymes
(a) TEM images of Fe3O4 NPs with three different sizes. (b) The catalytic activity (left) and specific activity (right) of Fe3O4 NPs of three 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
