About this collection

The combination of molecular spectroscopies based on infrared absorption, Raman scattering, and fluorescence emission with metal nanostructures generating very high locally increased electric fields upon resonant excitation, has led to novel types of spectroscopies with promising technological applications. There has been recent progress in in many different fields, but there is an urgent need for bringing together scientists from these various disciplines (physics, chemistry, materials science, engineering, life sciences) together. This themed issue aims to cover the full range of topics from fundamentals to methods and applications bringing together leading scientists from all of the involved fields.

The Guest Editors for this themed collection are Rudolf Holze (Chemnitz University of Technology, Germany) and Sebastian Schlücker (University of Duisburg-Essen, Germany).
