Caption

The new optical nano-sensor can detect low concentrations of nitrogen dioxide very precisely - down to the parts-per-billion level (ppb). The measuring technique is built upon an optical phenomenon which is called a plasmon. It arises when metal nanoparticles are illuminated and absorb light of certain wavelengths.
