2017 UBM. Surface-enhanced Raman spectroscopy (SERS) is broadly used in various research fields ranging from biochemistry to art conservation science. The SERS phenomenon is based on localization and amplification of photons by localized surface plasmon resonances (LSPRs) of noble metals. Over the past decade, numerous SERS platforms, including nanoparticles and SERS substrates, have been developed. However, because of a lack of commonly accepted standards of their spectroscopic characterization, it is nearly impossible to compare and validate their plasmonic performance. In this review, we discuss why it is important to report three physical parameters for any newly developed SERS platform: Microscopic characterization and near- and far-field responses. We also provide a short overview of several newly developed SERS substrates that were created during the last decade. Finally, this review shows several intriguing examples of recently reported applications of SERS in plasmon-driven photocatalysis, art conservation, and forensics.
