The impact of food contaminants on ecosystems and human health has attracted widespread global attention, and there is an urgent need to develop reliable food safety detection methods. Recently, carbon dots (CDs) have been considered as a powerful material to construct sensors for chemical analysis. Based on the concept of resource conversion and sustainable development, the use of natural, harmless, and renewable materials for the preparation of CDs without the involvement of chemical hazards is a current hot topic. This paper reviews the research progress of green-derived CDs and their application in food safety biosensing. The fabrications of green-derived CDs using various biomasses are described in detail, and the application of CDs especially the sensing mechanisms of photoluminescence, colorimetric, electrochemiluminescence and other sensors are provided. Finally, existing shortcomings and current challenges as well as prospects for food safety monitoring are discussed. We believe that this work provides strong insight into the application of CDs in the sensing of various contaminants.
食品污染物对生态系统和人类健康的影响引起了全球广泛关注，因此迫切需要开发可靠的食品安全检测方法。最近，碳点（CDs）已被认为是构建用于化学分析的传感器的一种强大材料。基于资源转化和可持续发展的理念，使用天然、无害且可再生的材料来制备不涉及化学危害的 CDs 是当前的热门话题。本文综述了绿色衍生 CDs 的研究进展及其在食品安全生物传感中的应用。详细描述了各种生物量制备绿色衍生 CDs 的方法，并提供了 CDs 的应用，特别是光致发光、比色、电致化学发光等传感器的传感机制。最后，讨论了当前面临的挑战和对食品安全监测的展望。我们相信，这项工作为 CDs 在各种污染物传感中的应用提供了深刻的见解。
