Abstract.
Raman spectroscopy (RS) is an effective characterization technique for the detection of wide range of analytes due to its potential to provide figure-print spectra of variety of molecules by detecting the inelastic scattering of incident photons. However, the application of this spectroscopy is limited due to very low signal to noise ratio. To overcome this drawback one can use metallic structured surfaces or noble metal nanoparticles that enhances the scattering signal by several orders of magnitude. In this case we deal with the another branch of Raman spectroscopy – Surface Enhanced Raman Scattering (SERS). The interest in this topic is increasing as novel materials are found to be efficient for signal enhancement, such as dielectrics, core-shell nanoparticles, graphene etc. In this talk I will introduce the basics of SERS and will show how the signal can be enhanced when using randomly distributed particles and assembled on a predefined template.
