“… 4 As such, its detection in and eradication from the environment has become a major target. 5,6 As a means of eradicating highly toxic 4-NP, its conversion to less toxic derivative 4-AP by catalytic reductive degradation is particularly appealing because of the latter's contribution to the production of various antipyretic and analgesic drugs. 1 …”

“…Besides, the system having CD and 4-NP resulted in the splitting of the corresponding CD peak into two, along with the fluorescence quenching. At the same time, the CD solution turned colourless to yellow in the presence of both 2-NP and 4-NP [ 162 ].…”

Carbon dots (CDs) are optically active carbon-based nanomaterials. These nanomaterials can change their light emission properties in response to various external stimuli such as pH, temperature, pressure, and light. The CD’s remarkable stimuli-responsive smart material properties have recently stimulated massive research interest for their exploitation to develop various sensor platforms. Herein, an effort has been made to review the major advances made on CDs, focusing mainly on its smart material attributes and linked applications. Since the CD’s material properties are largely linked to their synthesis approaches, various synthesis methods, including surface passivation and functionalization of CDs and the mechanisms reported so far in their photophysical properties, are also delineated in this review. Finally, the challenges of using CDs and the scope for their further improvement as an optical signal transducer to expand their application horizon for developing analytical platforms have been discussed.

“…Colorimetric detection processes have been widely used for a variety of chemical contaminant analyses, in which a colour change constitutes evidence of the presence or absence of harmful substances. These methods have typically been used to detect toxic cations 27,28 and less frequently to detect anions and neutral molecules of environmental interest 29–33 . The most commonly used indicator units correspond to metal complexes, for which the detection process is associated with electronic transitions between partially occupied metal d orbitals and both occupied and unoccupied ligand orbitals.…”

The applications of functional polymers to different research fields have been increasing. An especially important application is the use of polymer‐based sensors for the chromogenic detection of compounds of environmental interest in water. Polymer matrix supports have been developed to improve the sensing capacity and performance of chromogenic sensors. Therefore, research in the area of sensor design and manufacturing for pollutant detection is increasingly interesting to many scientific communities ranging from biological and chemical sciences to engineering. This subject of this review is colorimetric sensors that enable the rapid and quantitative detection of different analytes within a laboratory setup. The applications of different types of polymer‐based sensors used in the chromogenic detection of compounds of environmental interest are reviewed and analysed. © 2021 Society of Industrial Chemistry.
