Organophosphorus pesticides (OPPs) are extensively used in agricultural production, and the contamination caused by their residues has raised significant concerns regarding potential threats to human health. Herein, a novel fluorescence nanoprobe based on an enzyme-mediated silver nanoparticle-modified metal organic framework (AgNPs@PCN-224) was successfully prepared for rapid detection of OPPs. Initially, AgNPs@PCN-224 were synthesized reducing nitrate (AgNO3) using sodium borohydride (NaBH4) embedded into luminescent PCN-224. This triggered inner filter effect, leading quenching. Meanwhile, under catalysis acetylcholinesterase (AChE) choline oxidase (CHO), acetylcholine (ATCh) decomposed hydrogen peroxide (H2O2), which could destroy AgNPs form Ag+ released from PCN-224 recovery. Instead, fenitrothion, OPP, inhibited AChE activity, allowing quenched be reactivated. Under current optimum conditions, intensity had good correlation (Y = -728.5370X + 2178.4248, R2 0.9869) over dynamic range fenitrothion concentrations 0.1 500 ng/mL, with LOD 0.037 ng/mL. In addition, anti-interference ability robustness proposed sensor verified monitoring tea recoveries 87.67-103.72% relative standard deviations (RSD) < 5.43%, indicating that system excellent prospects OPP determination practical applications. Furthermore, this work provides universal platform screening other enzyme inhibitors detect

Microbial degradation is a highly efficient and reliable approach for mitigating the contamination of sulfonylurea herbicides, such as chlorimuron-ethyl, in soil water. In this study, we aimed to assess whether Kj-mhpC plays pivotal role chlorimuron-ethyl. enzyme purified via prokaryotic expression exhibited highest catalytic activity chlorimuron-ethyl at 35 °C pH 7. Bioinformatic analysis three-dimensional homologous modeling were conducted. Additionally, presence Mg+ Cu2+ ions partially inhibited but Pb2+ completely enzymatic Kj-mhpC. LC/MS revealed that hydrolyzes ester bond resulting formation 2-(4-chloro-6-methoxypyrimidine-2-amidoformamidesulfonyl) benzoic acid. Furthermore, point mutation serine position 67 (Ser67) confirmed it key amino acid active site degrading This study enhanced understanding how degraded by microorganisms provided reference bioremediation environment polluted with
