Environmental pollutants are difficult to degrade and easy to accumulate, which pose a serious threat to human health and ecological environment. Therefore, the rapid and sensitive detection of pollutants is crucially important. Metal nanoclusters (MNCs) have shown good application prospects in the field of chemical sensing due to their small size, high stability, short preparation time and easy modification. As a new type of fluorescent nanomaterials, MNCs have attracted much attention in the field of pollutant detection. In this paper, the research progress of MNCs in detecting heavy metal ions, sulfides, cyanides, polynitroaromatics, formaldehyde, organic pesticides, bacteria and viruses in recent years is summarized, and the development prospect of MNCs is discussed.

环境污染物不易降解，不易积累，对人类健康和生态环境构成严重威胁。因此，快速而灵敏地检测污染物至关重要。金属纳米团簇（MNCs）由于其体积小，稳定性高，制备时间短和易于修饰而在化学传感领域显示出良好的应用前景。作为一种新型的荧光纳米材料，跨国公司在污染物检测领域引起了广泛的关注。本文综述了跨国公司近年来在检测重金属离子，硫化物，氰化物，多硝基芳烃，甲醛，有机农药，细菌和病毒方面的研究进展，并对跨国公司的发展前景进行了展望。
