Single-atom nanozymes (SANs) are a class of with metal centers that mimic the structure metalloenzymes. Herein, we report synthesis Zn–N–C SAN, which mimics action natural carbonic anhydrase enzyme. The two-step annealing technique led to content more than 18 wt %. Since act as active sites, this high loading resulted in superior catalytic activity. Zn-SAN showed CO2 uptake 2.3 mmol/g and final conversion bicarbonate 91%. was converted via biomimetic process by allowing its adsorption catalyst, followed addition catalyst HEPES buffer (pH = 8) start into HCO3–. Afterward, CaCl2 added form white CaCO3 precipitate, then filtered, dried, weighed. Active carbon MCM-41 were used controls under same reaction conditions. According findings, sequestration capacity 42 mg CaCO3/mg Zn-SAN. Some amino acids (AAs) binding affinity for Zn able suppress enzymatic activity blocking centers. This strategy detection His, Cys, Glu, Asp limits 0.011, 0.031, 0.029, 0.062 μM, respectively, hence utilized quantifying these AAs commercial dietary supplements.

Abstract Due to the low stability and high cost of some natural enzymes, nanozymes have been developed as enzyme‐imitating nanomaterials. Single‐atom are a class with metal centers that mimic structure metal‐based enzymes. Herein, Cu‐N‐C single‐atom nanozyme (SAN) is synthesized excellent peroxidase‐ enhanced oxidase‐like activities action galactose oxidase. Cu‐SAN demonstrates stereospecific activity akin oxidase by oxidizing D‐galactose primary alcohol but not L‐Galactose or other carbohydrates. The SAN can catalyze oxidation in presence oxygen, producing hydrogen peroxide sub‐product. produced then oxidizes 3,3′,5,5′‐tetramethylbenzidine catalyzed SAN, yielding typical blue product. relationship between absorbance concentration linear 1–60 µ m range detection limit 0.23 . This strategy be utilized diagnosis galactosemia disorder dairy commercial products. DFT calculations clarify Cu sites POD‐like reaction explain selectivity toward
