Surface Enhanced Raman Scattering

Surface Enhanced Raman Scattering (SERS) is a technique that makes it easier to detect small amounts of molecules. It works by placing those molecules on a rough metallic surface, usually made of gold or silver. When light hits this surface, it causes the molecules to vibrate in ways that can be measured. This vibration creates a unique “fingerprint” for each molecule, which helps scientists identify and analyze substances even in tiny quantities. SERS is useful in fields like chemistry, biology, and medicine for detecting drugs, diseases, or pollutants with high sensitivity and specificity.
