Giant electromagnetic field enhancement in specifically designed hot-spots plays a key role in chemical sensing via plasmon-assisted Raman spectroscopy. On page 2353, A. Toma and co-workers present novel 3D nanostar dimer structures that enable field confinement in highly localized regions, which are decoupled from the substrate surface by their elevated architecture. These nanostar dimers can be exploited for single/few molecules detection.
