Safe Appraisal of Carbon Nanoparticles in Pollutant Sensing

The quantification of different ranges of pollutants and contaminants in the environment has earned enormous progress in the past few years owing to its extensive necessity in the domain of public health, clinical research, occupational hygiene, and mankind’s welfare. The release of carcinogenic pollutants from industrial, agriculture, and various other sectors is one of the serious threats faced by human beings. For the safety of living beings, there is an urgent need for rapid, selective, and sensitive detection strategies for the screening of different types of pollutants. Out of numerous advanced functional nanoparticles, the fluorescent carbon-based nanoparticles have initiated a new approach for establishing easy, selective, and expeditious real-time analysis of pollutants. The purpose of this chapter is to examine the unique properties of carbon dots, which make it useful in the area of sensing. The profiling of multifunctional luminescent CDsat nanometric range has unlocked new horizons of development in materials science and nanoremediation. In particular, we review the chemical and physical properties of carbon dots and their extensive potential in the fate of perilous pollutants detection for a better and cleaner environment.
