Abstract As nanoscale materials with the function of catalyzing substrates through enzymatic kinetics, nanozymes are regarded as potential alternatives to natural enzymes. Compared protein‐based enzymes, exhibit attractive characteristics low preparation cost, robust activity, flexible performance adjustment, and versatile functionalization. These advantages endow them wide use from biochemical sensing environmental remediation medical theranostics. Especially in biomedical diagnosis, feature catalytic signal amplification provided by makes emerging labels for detection biomarkers diseases, rapid developments observed recent years. To provide a comprehensive overview progress made this dynamic field, here an diagnosis enabled is provided. This review first summarizes synthesis nanozyme then discusses main strategies applied enhance their activity specificity. Subsequently, representative utilization combined biological elements disease reviewed, including related metabolic, cardiovascular, nervous, digestive diseases well cancers. Finally, some development trends nanozyme‐enabled highlighted, corresponding challenges also pointed out, aiming inspire future efforts further advance promising field.

Since the discovery of ferromagnetic nanoparticles Fe3O4 that exhibit enzyme-like activity in 2007, research on nanoenzymes has made significant progress. With in-depth study various and rapid development related nanotechnology, have emerged as a promising alternative to natural enzymes. Within nanozymes, there is category metal-based single-atom nanozymes been rapidly developed due low cast, convenient preparation, long storage, less immunogenicity, especially higher efficiency. More importantly, possess capacity scavenge reactive oxygen species through mechanisms, which beneficial tissue repair process. Herein, this paper systemically highlights types metal their catalytic recent applications repair. The existing challenges are identified prospects future composed metallic nanomaterials proposed. We hope review will illuminate potential repair, encouraging sequential clinical translation.

Traditional antibacterial agents are often observed to be ineffective because bacteria evolved strains with greater antibiotic resistance. Here, vigorous chitosan‐stabilized PtAu nanoparticles (CSPA) multienzyme‐like activity successfully fabricated, which serve an effective artificial nanozyme enhance for mixed bacterial infection wound treatment. Ultrasmall size CSPA exhibits excellent hydrophilicity and biocompatibility, possesses strong oxidase‐ peroxidase‐like generating a substantial amount of ROS (, 1 O 2 , ·OH) cause oxidative damage bacteria, also demonstrates nicotinamide adenine dinucleotide dehydrogenase‐like disrupting the respiratory chains, subsequently impedes adenosine triphosphate production. favorable broad‐spectrum at very low concentrations, prevents resistance, completely inhibits biofilm formation. Antibacterial Mechanism by transcriptomics is further revealed that can induce stress, hinder energy metabolism, disrupt synthesis function cell walls membranes. In vivo, population site promotes healing in rats. This study introduces novel approach, providing important insight into mechanism nanozymes promoting advancement nanocatalytic materials biomedical applications.

Single‐atom nanozymes (SANs) combine the natural enzymatic properties of nanomaterials with atomic distribution metallic sites over a suitable support. Unfortunately, their synthesis is complicated by some key factors, like poor loading, aggregation, time consumption, and low yield. Herein, copper SANs, surface metal loading (1.47% ± 0.16%) are synthesized, through green, facile, minimal solution processing, single‐step procedure, using CO 2 laser to promote anchoring precursor while simultaneously generating laser‐scribed graphene (LSG) support out polyimide sheet. The presence Cu on LSG verified high‐angle‐annular dark‐field–scanning transmission electron microscopy X‐ray photoelectron spectroscopy. To explore advantages incurred incorporation SANs LSG, material used as working electrode an electrochemical sensor for amperometric detection H O , achieving limit 2.40 μM. findings suggest that CuSANs can confer enhanced sensitivity which essential oxidative stress assessment, reaching values up 130.0 μA mM −1 cm −2 .
