Abstract

The detection of pefloxacin (PEF) in milk is of significant importance for food safety. Traditional methods for detecting PEF often rely on techniques such as high-performance liquid chromatography (HPLC), which are complex and time-consuming. This article introduces a surface-enhanced Raman scattering (SERS) substrate based on a composite of covalent organic frameworks (COFs) and silver nanoparticles (AgNPs) for the rapid detection of PEF in milk. After testing PEF in both water and milk, the detection limits were calculated to be 6.31 μg/L for water and 82 μg/L for milk, with correlation coefficients of 0.991 and 0.998, respectively. Furthermore, the average recovery rate of PEF in milk ranged from 96.25% to 106.17%, with a relative standard deviation (RSD) of 4.32% to 8.88%. This work offers a simple and rapid method for detecting PEF in milk.

基于COFs@Ag的SERS底物快速检测培氟沙星

牛奶中培氟沙星（PEF）的检测对食品安全具有重要意义。传统的PEF检测方法通常依赖于高效液相色谱（HPLC）等复杂且耗时的技术。本文介绍了一种基于共价有机框架（COFs）和银纳米粒子（AgNPs）复合材料的表面增强拉曼散射（SERS）衬底，用于牛奶中PEF的快速检测。水和牛奶中PEF的检出限分别为6.31 μg/L和82 μg/L，相关系数分别为0.991和0.998。PEF在牛奶中的平均回收率为96.25% ~ 106.17%，相对标准偏差（RSD）为4.32% ~ 8.88%。本工作为牛奶中PEF的检测提供了一种简便、快速的方法。图形抽象

期刊介绍： Plasmonics is an international forum for the publication of peer-reviewed leading-edge original articles that both advance and report our knowledge base and practice of the interactions of free-metal electrons, Plasmons. Topics covered include notable advances in the theory, Physics, and applications of surface plasmons in metals, to the rapidly emerging areas of nanotechnology, biophotonics, sensing, biochemistry and medicine. Topics, including the theory, synthesis and optical properties of noble metal nanostructures, patterned surfaces or materials, continuous or grated surfaces, devices, or wires for their multifarious applications are particularly welcome. Typical applications might include but are not limited to, surface enhanced spectroscopic properties, such as Raman scattering or fluorescence, as well developments in techniques such as surface plasmon resonance and near-field scanning optical microscopy.
