Surface Enhanced Raman Spectroscopy

Surface Enhanced Raman Spectroscopy (SERS) is an advanced technique used to detect and identify molecules with high sensitivity. It works by amplifying the weak light signals (Raman scattering) when molecules are near specially prepared metal surfaces, like gold or silver nanoparticles. These surfaces enhance the interaction of light with the molecules, producing a stronger signal that reveals their unique molecular fingerprint. SERS is valuable in fields like chemistry, medicine, and environmental testing because it allows for precise detection of very small amounts of substances rapidly and accurately.
