Nitrogen dioxide (NO2) produced by hydrocarbon combustion has a significant adverse impact on human health and the environment. In the current work, we developed a high-performance (limit of detection: 0.1 ppm), on-site, rapid NO2 gas sensor that could be operated under ambient conditions by combining a highly sensitive 3D porous SERS substrate and a handheld Raman spectrometer.
