| Abstract | ||||
| Colorimetric chemosensors and fluorescent probes have gained popularity in recent years as a quick, cost-effective, and simple method for detecting and monitoring toxic species such as metal cations, anions, and toxic gases. This approach offers a more straightforward alternative to complex and time-consuming analytical techniques. Heavy metal ions pose a significant environmental threat due to their potential risks to ecosystems and human health. This review focuses on the latest advancements in colorimetric chemosensors using rhodamine derivatives for the detection of metal cations. The review discusses the synthesis, detection limit, sensitivity, and binding mechanism of rhodamine-based chemosensors with metal ions from 2010 to 2025. While these sensors have shown promise, there is still room for improvement in terms of repeatability and sensitivity. The goal of this review is to inspire researchers to explore new possibilities for enhancing rhodamine-based chemosensors in the future. | ||||
