How Do Nanotechnology-Based Air Quality Sensors Work?
Nanotechnology-based sensors utilize nanoscale materials like carbon nanotubes, metal oxide nanoparticles, and nanowires. These materials have large surface areas and unique electrical, chemical, and physical properties. When air pollutants interact with these nanomaterials, they cause measurable changes in properties like electrical resistance, optical absorption, or fluorescence, which can be quantified to determine pollutant concentrations.
