Heart of gold : Surface‐enhanced fluorescence (SEF) is demonstrated with silica‐coated gold nanoparticles (SHINEF) that act as “smart dust” on the surface of a Langmuir–Blodgett monolayer. Coating gold nanoparticles of different sizes and shapes opens a wide range of applications for SEF, where the shape of the core with an appropriate thickness of the coating can be tuned for specific tasks.
