How Does Surface-Enhanced Raman Spectroscopy (SERS) Improve Detection?
Surface-Enhanced Raman Spectroscopy (SERS) significantly enhances the Raman scattering signal, often by factors of up to 10^6-10^8. This enhancement is achieved by using nanostructured metallic surfaces, typically gold or silver, which amplify the Raman signal of molecules adsorbed on their surface. SERS is especially valuable in detecting low-concentration analytes and has profound applications in biochemical sensing and diagnostic fields.
