Surface-enhanced Raman scattering
We present an introduction to surface-enhanced Raman scattering (SERS) which reviews the basic experimental facts and the essential features of the mechanisms which have been proposed to account for the observations. We then review very recent fundamental developments which include: SERS from single particles and single molecules; SERS from fractal clusters and surfaces; and new insights into t...
متن کاملSurface-enhanced Raman scattering
© 2007 American Institute of Physics, S-0031-9228-0711-020-6 When light interacts with matter, it can scatter inelastically from vibrational quantum states. During that process, photons may lose energy to, or gain it from, vibrational excitations. A change in the photon energy must produce a concomitant shift in the frequency of the scattered light (see box 1). The phenomenon, called the Raman ...
متن کاملSurface-enhanced Raman scattering
On the basis of different types of experiments, we develop implicitly the model of surfaceenhanced Raman scattering (SERS) of adsorbates on metal s u r f a c g . The long-range enhancement by resonances of the macroscopic laser and Stokes field is separated quantitatively from the metal eledmn-mediated resonance Raman effect. The latter mechanism proceeds b y increased electron-photon coupling ...
متن کاملQuantitative Detection of NADH Using a Novel Enzyme-Assisted Method Based on Surface-Enhanced Raman Scattering
An enzymatic method for quantitative detection of the reduced form of nicotinamide-adenine dinucleotide (NADH) using surface-enhanced Raman scattering was developed. Under the action of NADH oxidase and horseradish peroxidase, NADH can generate hydrogen peroxide (H₂O₂) in a 1:1 molar ratio, and the H₂O₂ can oxidize a chromogen into pigment with a 1:1 molar ratio. Therefore, the concentration of...
