Sers physics
Web1 Sep 2024 · SERS has found application in a number of biological studies due to the ability to detect specific biomolecules and events at high sensitivity and in a multiplexed format. This session will set out some of the latest breakthroughs in using SERS for biological applications including immunoassays and ultra sensitive biomolecular detection. WebSurface-enhanced Raman scattering (SERS) is one of the strongest and most enigmatic effects in physics and optics, see the excellent review [1]. It was dis-covered approximately thirty years ago [2,3,4]. The SERS is manifested as an enhancement by many orders of magnitude of the intensity of Raman ra-
