Heavy and transition metal (HTM) ions have significant harmful effects on the physical environment and play crucial roles in biological systems; hence, it is crucial to accurately identify and quantify any trace pollution. Molecular sensors which are based on organic molecules employed as optical probes play a crucial role in sensing and detecting toxic metal ions in water, food, air, and biological environments. When appropriate combinations of conduction and selective recognition are combined, fluorescent and colorimetric chemosensors are appealing instruments that enable the selective, sensitive, affordable, portable, and real-time investigation of the possible presence of heavy and transition metal ions. This feature article aims to provide readers with a more thorough understanding of the different methods of synthesis and how they work. As noted in the literature, we will highlight colorimetric and fluorometric sensors based on their receptors into multiple categories for heavy metal ion detection, such as Hg, Ag, Cd Pb, and In, and simultaneous multiple-ion detection.
重金属和过渡金属（HTM）离子对自然环境有重大危害，且在生物系统中起着关键作用；因此，准确识别和量化任何痕量污染至关重要。基于有机分子作为光学探针的分子传感器在水、食品、空气和生物环境中检测有毒金属离子方面发挥着关键作用。当传导与选择性识别适当结合时，荧光和比色化学传感器是很有吸引力的工具，能够对重金属和过渡金属离子的可能存在进行选择性、灵敏、经济、便携和实时的检测。这篇专题文章旨在让读者更全面地了解不同的合成方法及其工作原理。正如文献中所指出的，我们将基于其受体将用于重金属离子检测（如汞、银、镉、铅和铟）的比色和荧光传感器分为多个类别，并介绍同时进行多离子检测的情况。
