A comprehensive review on colorimetric and fluorometric investigations of dual sensing chemosensors for Cu and Fe ions from the year 2017 to 2023.

Dual sensing chemosensors for copper(II) and iron(III) ions are molecules or compounds designed to selectively detect and differentiate between these specific metal ions. Because metal ions like copper(II) and iron(III) are essential to so many industrial, biological, and environmental processes, their detection and measurement have become increasingly important. In this work, a novel dual-sensing chemosensor that combines high selectivity and sensitivity is presented.
