Tetracycline (TC) has been widely used in clinical medicine and animal growth promotion due to its broad-spectrum antibacterial properties and affordable prices. Unfortunately, the high toxicity and difficult degradation rate of TC molecules make them easy to accumulate in the environment, which breaks the ecological balance and seriously threatens human health. Rapid and accurate detection of TC residue levels is important for ensuring water quality and food safety. Recently, fluorescence detection technology of TC residues has developed rapidly. Lanthanide nanomaterials, based on the high luminescence properties of lanthanide ions and the high matching with TC energy levels, are favored in the real-time trace detection of TC due to their advantages of high sensitivity, rapidity, and high selectivity. Therefore, they are considered potential substitutes for traditional detection methods. This review summarizes the synthesis strategy, TC response mechanism, removal mechanism, and applications in intelligent sensing. Finally, the development of lanthanide nanomaterials for TC fluorescence detection and removal is reasonably summarized and prospected. This review provides a reference for the establishment of a method for the accurate determination of TC content in complex food matrices.
四环素（TC）因其广谱抗菌特性和价格实惠而被广泛应用于临床医学和动物生长促进。然而，TC 分子的高毒性和难降解率使其容易在环境中积累，破坏了生态平衡，严重威胁着人类健康。快速准确地检测 TC 残留水平对于确保水质和食品安全至关重要。最近，TC 残留的荧光检测技术发展迅速。基于镧系离子的高发光性能和与 TC 能级的高度匹配，镧系纳米材料在 TC 的实时痕量检测中受到青睐，因为它们具有高灵敏度、快速性和高选择性的优点。因此，它们被认为是传统检测方法的潜在替代品。本综述总结了 TC 响应机制、去除机制及在智能传感中的应用。最后，对镧系纳米材料用于 TC 荧光检测和去除的发展进行了合理的总结和展望。本综述为建立复杂食品基质中 TC 含量的准确测定方法提供了参考。
