Abstract

Paracetamol (PCM) is a commonly used analgesic and antipyretic agent for humans worldwide. However, PCM overdoses or overuse can cause health issues, such as hepatoxicity. As PCM is also used for the treatment of farm animals, it is essential to monitor these residues in animal-derived matrices at risk-based sites in order to minimize the intake of PCM through the food chain. In the present study, we have developed a novel carbon nanoparticle (CNP)-based indirect competitive lateral flow immunoassay (icLFIA) for the rapid detection of PCM in bovine urine. The developed icLFIA can detect PCM residues within 10 min, and its performance was validated according to Commission Implementing Regulation (EU) 2021/808, i.e., determination of the detection capability (CCβ), specificity, robustness, and stability. The CCβ of the icLFIA for PCM in bovine urine is 5 mg/L and the icLFIA is proven to be selective and specific towards PCM in bovine urine, as no matrix interference and cross-reactivity were observed, except for high concentrations of orthocetamol. The icLFIA for PCM in bovine urine is robust to (small) variations in reading time, but it remains necessary to strictly use a dilution ratio of running buffer/bovine urine of 80/20. Moreover, the produced icLFIAs are stable for at least 56 days under the stored conditions. In conclusion, the developed and validated icLFIA provides a rapid and cost-effective method for on-site monitoring of PCM abuse in cattle.

牛尿中对乙酰氨基酚（扑热息痛）的间接竞争侧流免疫测定方法的开发和验证。

扑热息痛（PCM）是世界范围内人类常用的镇痛解热药物。然而，PCM过量或过度使用会导致健康问题，如肝毒性。由于PCM也用于治疗农场动物，因此必须在基于风险的地点监测动物来源基质中的这些残留物，以尽量减少通过食物链摄入PCM。在本研究中，我们开发了一种基于碳纳米颗粒（CNP）的间接竞争侧流免疫分析法（icLFIA），用于快速检测牛尿液中的PCM。所开发的icLFIA可在10 min内检测PCM残留，其性能根据欧盟委员会实施法规（EU） 2021/808进行了验证，即检测能力（CCβ）、特异性、鲁棒性和稳定性的测定。icLFIA对牛尿中PCM的CCβ为5 mg/L，对牛尿中的PCM具有选择性和特异性，除了高浓度的正辛胺外，没有观察到基质干扰和交叉反应。牛尿中PCM的icLFIA对读取时间的（小）变化是稳健的，但仍然有必要严格使用运行缓冲液/牛尿的稀释比为80/20。此外，制备的iclfia在储存条件下至少可以稳定56天。总之，开发和验证的icLFIA为现场监测牛体内PCM滥用提供了一种快速、经济的方法。
