Review:
Surface Enhanced Raman Spectroscopy (sers)
overall review score: 4.2
⭐⭐⭐⭐⭐
score is between 0 and 5
Surface-Enhanced Raman Spectroscopy (SERS) is an advanced analytical technique that significantly amplifies the Raman scattering signals of molecules adsorbed on nanostructured metallic surfaces, typically gold or silver. This enhancement enables highly sensitive detection of chemical and biological substances at trace levels, making SERS a powerful tool in various fields such as chemical sensing, biomedical diagnostics, environmental monitoring, and food safety.
