Rapid and sensitive detection of foodborne pathogenic bacteria is particularly important for the prevention and control of foodborne diseases. The lateral flow strip biosensor (LFSB) is one of the most promising point-of-care detection tools and has been widely used in food safety monitoring. This review introduces recent advances in the detection of foodborne pathogenic bacteria using LFSBs. According to different bacterial biomarkers, we summarize the direct and indirect sensing strategies of bacterial LFSBs. The direct sensing strategies for whole bacterial cells are divided into antibodies, antibody alternatives, and label-free according to the recognition elements. The indirect sensing strategies refer to the detection of bacterial nucleic acids and metabolites. Next, we compare and discuss the applications of direct and indirect sensing strategies. Finally, the existing challenges, future perspectives, and development directions are discussed, which will facilitate the theoretical innovation and practical application for bacterial LFSBs.

通过直接和间接传感策略检测食源性致病菌的侧流条生物传感器：综述

快速、灵敏地检测食源性致病菌对于食源性疾病的预防和控制尤为重要。侧流试纸条生物传感器（LFSB）是最有前途的即时检测工具之一，已广泛应用于食品安全监测。本文介绍了使用 LFSB 检测食源性致病菌的最新进展。根据不同的细菌生物标志物，我们总结了细菌LFSB的直接和间接传感策略。全细菌细胞的直接传感策略根据识别元件分为抗体、抗体替代和无标记。间接传感策略是指细菌核酸和代谢物的检测。下一个，我们比较并讨论了直接和间接传感策略的应用。最后，讨论了细菌LFSB现有的挑战、未来的前景和发展方向，这将有助于细菌LFSB的理论创新和实际应用。
