Abstract

In recent years, the spread of pollutants including toxins, pesticides, or heavy metal ions in soil, water, and air environments has been increasing. Environmental contamination issues are very important for human health. For this reason, it is necessary to fabricate a quick detection and real-time monitoring system for hazardous compounds via high correctness and sensitivity in the environmental sample. Methods that provide the detection of hazardous compounds in real time by using a colorimetric sensor that is also visual by the naked-eye are extremely required for applications of environmental control. Plasmonic nanoparticles can be used to detect these hazardous compounds. Nanomaterials display unique features. In recent years, noble metal nanoparticles have attracted attention due to their physicochemical features and applications in areas including biotechnology, electronics, catalysis, and plasmonic. The surface plasmon resonance features of silver and gold nanomaterials have been helpful for a kind of application. Plasmonic nanoparticles have recently been utilized as favorable materials in colorimetric detection methods. As a result, rapid and sensitive detection of hazardous compounds and small contaminants without the requirement of anyone device (i.e., naked-eye watching change of colors) can be achieved using a UV–visible spectrophotometer. Herein, this chapter summarizes the importance of plasmonic nanoparticles and the use of these materials in environmental monitoring and analysis is extensively discussed.
