The special pathological microenvironment of infected wounds (pathology weakly acidic, hypoxic, and overexpressed H2O2) provides fertile soil for the development disease. Tailoring treatment based on specific characteristics infectious (IME) has emerged as a novel direction in antimicrobial therapies. Here, polyoxovanadate (POV)-based covalent organic polymer (POV-Fc-COP) with inherent photothermal activity was facilely prepared via copolymerization 1,1′-bi(3-dimethylamino-1-oxo-2-enyl-ferrocene) (BDOEF) tris-NH2-modified POV (tris-V6O9), which nanovanadium oxide (V2O3 V2O5) core shell were generated directly during Michael addition–elimination reaction. unique structure composition impart pH-responsive peroxidase-like (POD-like) catalase-like (CAT-like) activities, concurrently, to POV-Fc-COP. Specifically, acid-activated mimicking-POD could consume H2O2 microenvironment, producing toxic •OH combat bacteria biofilms. vanadium consumes excessive acid, resulting an increase pH. Meanwhile, CAT-like transform excess expression into O2 relieve hypoxia induced by damage blood vessels facilitate wound healing. Additionally, synergistic amplified therapeutic effect triggered application laser irradiation facilitates rapid eradication biofilm, minimizing detrimental impacts bacterial proliferation IME, thereby accelerating restoration IME return normal state. Therefore, POV-Fc-COP dual-enzyme functionality not only utilize but also regulate significantly expediting healing bacteria-infected wounds. This study demonstrates simple method preparation intelligent platform programmed antibacterial antibiofilm formation, thus promoting while utilizing improving IME.

Organophosphorus pesticides are the most extensively utilized agrichemicals in world. They play a crucial role regulating crop growth, immunizing against pests, and improving yields, while their unregulated residues exert serious detrimental effects on both environment human health. Many efforts have been made world to monitor organophosphorus solve issues caused by them. Nanozymes, as one kind of enzyme mimic that is artificially designed simulate function natural enzymes, aroused lot attention due unparalleled advantages. Nanozymes inherit unique properties nanomaterials catalytic functions, which could overcome limitations inherent enzymes great versatile adaptable application prospects. This review presents recent advancement synthesizing multifunctional nanozymes with enzymatic-like activities using various degrade detect pesticides. It mainly encompasses metal-based nanozymes, carbon-based metal-organic-framework-based single-atom-based nanozymes. Additionally, this paper discusses potential novel functional environmental materials.
