Pesticide residues pose a significant threat to food safety and human health, necessitating the development of novel detection tools. Pesticides can inhibit the activity of certain biological enzymes, so enzyme inhibition is one of the methods of pesticide detection. In this study, we developed a novel near-infrared fluorescent probe named TCFCl-CES based on the tricyanofuran structure, for ultrasensitive detection of carboxylesterase (CES). TCFCl-CES exhibits strong and stable fluorescence, excellent specificity. Notably, the fluorescence intensity of TCFCl-CES shows a linear relationship with CES concentration, achieving an exceptionally low detection limit of 4.41 × 10–5 u/mL. This ultrasensitive probe can also effectively detect pesticide residues in vegetables and monitor CES activity in cells and liver tissues. TCFCl-CES stands out for its rapid and accurate detection capabilities, making it an essential tool for accurately monitoring pesticide residue. It also has great potential for tracking CES activity in biological systems. Additionally, it offers a robust solution for food safety and improving pesticide residue analysis.

用于羧酸酯酶生物成像和检测食品中农药残留的新型超灵敏荧光探针
农药残留对食品安全和人类健康构成重大威胁,需要开发新型检测工具。农药能抑制某些生物酶的活性,因此酶抑制是农药检测的方法之一。在这项研究中,我们开发了一种基于三氰基呋喃结构的新型近红外荧光探针TCFCl-CES ,用于超灵敏检测羧酸酯酶(CES)。 TCFCl-CES荧光强度强且稳定,特异性优异。值得注意的是, TCFCl-CES的荧光强度与 CES 浓度呈线性关系,实现了 4.41 × 10 –5 u/mL 的极低检测限。这种超灵敏探针还可以有效检测蔬菜中的农药残留,并监测细胞和肝组织中的CES活性。 TCFCl-CES以其快速、准确的检测能力而脱颖而出,使其成为准确监测农药残留的重要工具。它在跟踪生物系统中的 CES 活动方面也具有巨大的潜力。此外,它还为食品安全和改进农药残留分析提供了强大的解决方案。
