Food safety is essential for sustaining a healthy life, with foodborne pathogens representing a principal factor contributing to food safety risks, thereby posing a formidable threat to human health that cannot be overlooked. According to the U.S. Centers for Disease Control statistics, the U.S. has caused a cumulative total of more than 9.6 million foodborne illnesses, a variety of foodborne pathogens enter the human body along with eating, endangering people's physical and mental health, but also add a huge burden on society. Traditional detection techniques are time-consuming, labor-intensive, and heavily dependent on expensive equipment. Therefore, to protect people's lives and health, many scholars around the world have been exploring how to develop efficient, convenient, and low-cost foodborne pathogens detection technologies. In the process of exploration, carbon dots (CDs), as a new type of nanoparticles, have gradually become an excellent choice for pathogenic microbial detection due to their unique optical and physicochemical properties as well as low toxicity. The detection of foodborne pathogens based on CDs can be efficiently achieved through electrochemical or fluorescent biosensors. This review not only elucidates the preparation of CDs but also succinctly summarizes their application in CDs-based electrochemical and fluorescent biosensors for detecting foodborne pathogens. It delves into the underlying working mechanisms, outlines the advantages, and discusses the limitations of these sensors. In addition, the urgent problems that need to be solved in the practical application of CDs-based biosensors and the future exploration directions are also elaborated.

基于碳点的电化学和荧光生物传感器检测食源性病原体:当前进展和挑战
食品安全对于维持健康生活至关重要,食源性病原体是导致食品安全风险的主要因素,因此对人类健康构成了不容忽视的巨大威胁。根据美国疾病控制中心的统计,美国累计造成了超过 960 万例食源性疾病,多种食源性病原体随食进入人体,危害人们的身心健康,也给社会增加了巨大的负担。传统的检测技术耗时、劳动密集,并且严重依赖昂贵的设备。因此,为了保护人们的生命和健康,世界各地的许多学者一直在探索如何开发高效、方便、低成本的食源性病原体检测技术。在勘探过程中,碳点 (CDs) 作为一种新型纳米颗粒,由于其独特的光学和物理化学性质以及低毒性,逐渐成为病原微生物检测的绝佳选择。通过电化学或荧光生物传感器,可以有效地实现基于 CD 的食源性病原体检测。本文不仅阐明了 CDs 的制备,还简要总结了它们在基于 CDs 的电化学和荧光生物传感器检测食源性病原体中的应用。它深入探讨了底层工作机制,概述了其优点,并讨论了这些传感器的局限性。此外,还阐述了基于 CDs 的生物传感器在实际应用中亟待解决的问题和未来的探索方向。
