Abstract

Contaminant residues in food and drinking water pose a significant threat to human health. Therefore, high-performance, on-site analytical methods are essential for effectively monitoring and controlling this risk. In recent years, photothermal lateral flow immunoassay (LFIA) has garnered considerable attention as a point-of-care testing (POCT) method due to its rapid responsiveness, cost-effective portable instrumentation, and operational simplicity. In this context, considerable efforts have been dedicated to advancing photothermal LFIAs for food safety and control. This review aims to summarize the principles and assay formats of LFIAs, along with the sensing mechanisms underlying photothermal LFIAs. Furthermore, it provides an overview of recent developments in the functional modification of photothermal materials within LFIA systems for detecting harmful substances in food, including pathogenic bacteria, mycotoxins, hazardous organic pollutants, veterinary drug residues, and other organic contaminants. Additionally, the future directions and recent challenges hindering the practical application of photothermal LFIAs are briefly summarized.

光热技术在横向流动免疫分析中的意义：发展及其在食品安全分析中的应用。

食品和饮用水中的污染物残留对人类健康构成重大威胁。因此，高效的现场分析方法对于有效监测和控制这种风险至关重要。近年来，光热侧流免疫分析法（LFIA）作为一种即时检测（POCT）方法，由于其快速响应、成本效益高、便携式仪器和操作简单，引起了相当大的关注。在此背景下，人们致力于推进用于食品安全和控制的光热LFIAs。本文综述了LFIAs的原理和检测格式，以及光热LFIAs的传感机制。此外，它还概述了用于检测食品中有害物质（包括致病菌、真菌毒素、有害有机污染物、兽药残留和其他有机污染物）的LFIA系统中光热材料功能改性的最新进展。此外，还简要总结了光热LFIAs实际应用的未来方向和当前面临的挑战。

期刊介绍： Critical Reviews in Analytical Chemistry continues to be a dependable resource for both the expert and the student by providing in-depth, scholarly, insightful reviews of important topics within the discipline of analytical chemistry and related measurement sciences. The journal exclusively publishes review articles that illuminate the underlying science, that evaluate the field''s status by putting recent developments into proper perspective and context, and that speculate on possible future developments. A limited number of articles are of a "tutorial" format written by experts for scientists seeking introduction or clarification in a new area. This journal serves as a forum for linking various underlying components in broad and interdisciplinary means, while maintaining balance between applied and fundamental research. Topics we are interested in receiving reviews on are the following: · chemical analysis; · instrumentation; · chemometrics; · analytical biochemistry; · medicinal analysis; · forensics; · environmental sciences; · applied physics; · and material science.
