Abstract

This document briefly introduces the key concepts to understand the phenomenon of fluorescence enhancement with optical nanostructures. The equations remain simple, with the major goal to illustrate the different physical effects at play. It also provides an overview of different recent approaches to enhance single molecule fluorescence with plasmonic and non-plasmonic nanoantennas, and describes three main biochemical applications.
