Plasmonic substrates for surface enhanced Raman scattering.
As an advanced analytical tool, surface-enhanced Raman scattering (SERS) has broad applications in identification of colorants in paints and glazes, hazard detection to ensure food safety, biomedicine and diagnosis, environmental monitoring, detection of explosives and forensic science. In this review, main types of plasmonic substrates, which include solid substrate with metallic nanostructure...
متن کاملSurface Enhanced Raman Spectroscopy
Raman spectroscopy is the use of inelastic scattering of light to probe various properties of molecules and materials. Incoming photons interact with the electron cloud of the molecular bonds and inelastically scatter. During this scattering the energy of the incoming photon is shifted to red or blue depending on the particular process. This phenomenon is called Raman scattering and was discove...
متن کاملSurface-enhanced Raman spectroscopy.
The ability to control the size, shape, and material of a surface has reinvigorated the field of surface-enhanced Raman spectroscopy (SERS). Because excitation of the localized surface plasmon resonance of a nanostructured surface or nanoparticle lies at the heart of SERS, the ability to reliably control the surface characteristics has taken SERS from an interesting surface phenomenon to a rapi...
متن کاملRoom-temperature sensor based on surface-enhanced Raman spectroscopy.
As reported in the literature, several factors, such as scattering cross sections, polarisability and wavelength suitability, contribute to increased SERS enhancement. In general, the advantage of surface-enhanced Raman scattering (SERS)-active Ag nanoparticles (NPs) is their higher SERS enhancement over Au NPs because the molar extinction coefficient of the Ag NPs is the highest of its kind am...
متن کاملSurface Enhanced Raman Scattering Spectroscopy
This review covers from the basic principles of Raman spectroscopy to the advanced technique of surface enhanced Raman Scattering (SERS) spectroscopy. After briefly going through the description of Raman and introduction of the development of SERS, the article will focus on the “hotspot” of the current research work on SERS – single molecule spectroscopy. We will see later that “hotspot” is als...
