Surface 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 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...
متن کاملOlive Oil Adulteration Sensing by Ftir and Raman Spectroscopy
The adulteration of extra virgin olive oil with cheaper oils is a major problem in the olive oil market. In the present work, experimental determinations of low cost vegetable oils content in extra virgin olive oils (EVOO) were performed by Fourier Transform Infrared (FTIR) spectrometry and Raman spectrometry. To this purpose, a set of pure oils and mixtures of extra-virgin oils and different v...
متن کاملBiosensing Based on Surface-Enhanced Raman Spectroscopy by Using Metal Nanoparticles
Surface-enhanced Raman spectroscopy (SERS) is a promising tool in the analytical science because it provides good selectivity and sensitivity without the labeling process required by fluorescence detection. This technique consists of locating the target analyte on nanometer range of roughed Au-nanoparticles. The presence of the metal nanoparticles provides a tremendous enhancement to the result...
