SERS active substrates

SERS (Surface-Enhanced Raman Scattering) active substrates are specially designed surfaces that amplify the detection of molecules through laser-based spectroscopy. These substrates typically consist of nanostructured metals like gold or silver, which create intense electromagnetic fields when illuminated. When molecules are close to these nanostructures, their vibrational signals become significantly stronger, allowing for highly sensitive and precise identification of substances at very low concentrations. SERS active substrates are essential in fields like chemical analysis, environmental monitoring, and medical diagnostics for their ability to detect trace amounts of analytes efficiently.
