Nano-structured, reusable substrate for ultra-sensitive detection of pollutants

Surface-enhanced Raman scattering (or spectroscopy), known as SERS, is an advanced analysis method that extends the range of Raman applications to trace analysis, such as part-per-million-level detection of a pollutant in water or different liquids. SERS has a high potential to be used in the fields of biochemistry, forensics, food safety, threat detection and medical diagnostics.
