Surface-enhanced Raman scattering (SERS) is a powerful analytical technique that enhances the Raman scattering signal of molecules adsorbed on rough metal surfaces or nanostructures, often increasing the intensity by many orders of magnitude. This enhancement allows for the detection of low-concentration analytes, making SERS a valuable tool in fields such as chemistry, biology, and materials science.

Nanostructures are materials or devices with at least one dimension on the nanoscale, typically ranging from 1 to 100 nanometers, which exhibit unique properties due to their size and surface effects. These structures are fundamental in advancing fields such as nanotechnology, materials science, and medicine, enabling innovations in drug delivery, electronics, and energy storage.
