How do Plasmonic Resonances Enhance Sensing Capabilities?
Plasmonic resonances enhance sensing capabilities through a phenomenon known as surface-enhanced Raman scattering (SERS). When molecules are adsorbed onto the surface of plasmonic nanoparticles, the local electromagnetic field is significantly enhanced, leading to an increase in the Raman signal. This allows for the detection of even single molecules, making SERS a powerful tool in chemical and biological sensing.
