Abstract
The emission of volatile organic compounds (VOCs) from a variety of sources, including routinely used products, poses serious health risks. Moreover, it is of prime importance to develop monitoring and detecting systems. Sensors play a crucial role in improving environmental quality by monitoring these pollutants. Nanomaterials are an excellent choice for sensing because of their ease of production, chemical diversity, and ability to be easily integrated into a variety of sensing systems. Furthermore, they provide better stability and detect trace amounts of gases present in the surroundings. Here, we present a concise discussion on the functional nanomaterials that can be employed for sensing purposes. The principle criteria involve (1) the use of various nanomaterials based on metal oxides, conjugate polymers, and carbon-based materials and (2) tuning the properties through various engineering methods. It discusses the recent efforts as well as future alternatives toward highly selective sensing systems.
