O efeito SERS na análise de traços: o papel das superfícies nanoestruturadas The SERS effect in trace analysis: the role of nanostructured surfaces

Abstract

Surface-Enhanced Raman Scattering - SERS - underwent huge advances since a single-molecule Raman spectrum was obtained in 1997. New theoretical and experimental approaches emerged since then leading to a better understanding of the enhancement mechanisms and to a significant improvement in the Raman signal. This review presents the current status of the SERS effect and the promising ways of designing and preparing high performance SERS-active substrates.
