SERS Spectroscopy and Microscopy


This chapter discusses surface-enhanced Raman scattering (SERS) spectroscopy and microscopy. By coupling the SERS spectroscopy with the microscopic investigation, performances and applications of this technique can be largely amplified. Coupling SERS experiments and microscopic measurements allows obtaining important information on the mechanisms of the Raman enhancement, as well as on the properties of both adsorbates and metal surfaces, where ligand molecules adhere. The Raman spectra on solid metal substrates were measured using a Renishaw RM2000 micro-Raman apparatus, coupled with a diode laser source emitting at 785 nm. The importance of transmission electron microscopy (TEM), scanning electron microscopy (SEM), and atomic force microscopy (AFM) analyses are briefly presented in relation to some SERS studies on different substrates. SERS spectroscopy may also provide fundamental information in the mineralogical analysis on rocks and soils, allowing the identification of the different minerals constituting the rock matrix and the chemical and structural composition of these minerals. Some applications of SERS microspectroscopy are reviewed, by considering that this technique is being liable of new perspectives and evolution in the future of micro-analysis. Finally, it has to be highlighted that the micro-SERS performances can be greatly implemented by combining the spectroscopic measurements with the “mapping” and “imaging” techniques, already present in the modern instrumentations.
