About this collection

Guest edited by Professor Karen Faulds, University of Strathclyde, UK
The articles collected in this themed issue are focused on the technique of surface enhanced Raman scattering (SERS). Since the discovery of the SERS effect over 40 years ago, the technique has developed into an information rich and sensitive technique for the detection of trace analytes and biomolecules. This themed collection spans the range of enhancing materials and applications of SERS from synthesis of novel metal nanoparticles and surfaces to the development of specific assays for the detection of analytes as well as further understanding of the theory of the enhancement effect.
