SERS (Surface Enhanced Raman Spectroscopy)

Surface-Enhanced Raman Spectroscopy (SERS) is a technique that amplifies the detection of molecules by using tiny metallic structures, typically gold or silver nanoparticles. When light hits these nanostructures, it creates enhanced electromagnetic fields that boost the weak signals produced by molecules' vibrational fingerprints. This amplification allows for highly sensitive and precise identification of substances, even at very low concentrations. SERS is valuable in areas like medical diagnostics, environmental monitoring, and food safety, enabling the detection of trace molecules with remarkable accuracy.
