Carbon quantum dots (CQDs) are zero-dimensional quasi-spherical nanoparticles smaller than 10 nm, composed of carbon and various surface groups. These compounds are utilized in applications such as metal ion detection, photodegradation of pollutant, bio-imaging, and drug delivery, in order to their high solubility in water, optical stability, luminescence properties, and biocompatibility. Due to their fluorescent characteristics, carbon quantum dots can selectively respond to target molecules in environmental and biological samples. This article discusses the applications of carbon quantum dots across various fields, particularly their role as optical sensors for identifying one or more metal pollutants, either individually or simultaneously. It also explores the use of carbon quantum dots doped with one or more elements for detecting metal cations. Finally, the article examines the current challenges and future prospects of using carbon quantum dots as sensors.
