Single-atom nanozymeAs a high biologically toxic heavy metal ion, Cr(VI) will cause environmental pollution and endanger human health. Therefore, the development of fast, simple and visible detection methods for Cr(VI) is extremely important to control its harm. Toward this end, we report the ...
Fig. 1: Single-atomic nanozymes with superior catalytic activities and selectivity beyond the natural enzymes were developed with unique definitive units. The bioactive sutures based on artificial enzymes showed catalytic recyclability and sustainability without evident decay in activities. They also accelerat...
Conventional nanozyme technologies face formidable challenges of intricate size-, composition-, and facet-dependent catalysis and inherently low active site density. We discovered a new class of single-atom nanozymes with atomically dispersed enzyme-like active sites in nanomaterials, which significantly enh...
Switching on-off-on colorimetric sensor based on Fe-N/S-C single-atom nanozyme for ultrasensitive and multimodal detection of Hg2+ Single-atomnanozymes (SAzymes) as a new class of efficient nanozymes have attracted extensive research interest due to their high catalytic activity and sp... R Li...

Here, we report an engineered FeNP-centred single-atom nanozyme (FeNP-SAzyme) that exhibits comparable peroxidase-like catalytic activity and kinetics to natural enzymes, by controlling the electronic structure of the single-atom iron active centre through the precise coordination of phosphorus and ...
–C support and planar 2D-FeCu–N–C nanozyme, respectively (Fig.4b). To elucidate the factors contributing to the enhanced OXD-like catalytic efficiency, a series of control analysis were performed to confirm the indispensability of each component in FePc@2D-Cu–N–C (Supplementary Figs.28...
CuO nanozyme (0.91 U mg−1), and almost 5-fold higher than that of Cu2O nanozyme (2.08 U mg−1) (Fig.3b). Conversely, Cu-free N-doped carbon support shows no significant catalytic performance under the same conditions (Supplementary Fig.12). These results indicate that regulating the ...
