In Situ Detection of Low Amounts of Ammonia

Ammonia (NH3) has gained tremendous importance in the chemical industry and affects human life in numerous aspects. In situ detection of ammonia is essential to industrial production and environmental monitoring, and is in urgent need of development. Surface-enhanced Raman scattering (SERS), as described by Liu et al., opens up new opportunities for low-concentration ammonia detection with high spatiotemporal resolution.
