Abstract Over more than 40 years since its discovery, surface‐enhanced Raman scattering/spectroscopy (SERS) has attracted substantial attention as a tool for fundamental research in surface science and potential analytical sensing applications. This review aims to concisely summarize the essential principles of both physical chemical processes underlying signal enhancement, well elements broader field plasmonics that are most relevant SERS. In order make sense overwhelming variety SERS platforms reported, fabrication, properties, operational enhancing substrates given particular here context specific application requirements. While high spatial precision lithographic techniques helped improve understanding plasmonic platforms, their prohibitive cost encouraged exploration facile fabrication methods widespread adoption Selected examples introduced illustrate common themes recur studies, applications, efforts produce stable, affordable, robust platforms.
