How Can Nanotechnology Help in Detecting Gaseous Pollutants?
Nanotechnology enables the development of highly sensitive and selective nanosensors that can detect gaseous pollutants at very low concentrations. These sensors often utilize nanomaterials such as carbon nanotubes, metal oxides, and graphene due to their high surface area and unique electronic properties. For example, tin dioxide (SnO2) nanoparticles are commonly used in gas sensors for detecting CO and NOx due to their high sensitivity and fast response times.
