Plasmonic nanopores are a particular family of nanocavities able to engineer
and confine electromagnetic fields to subwavelength volumes. In the past
decade, they have enabled a large set of applications, in particular for
sensing, optical trapping, and the investigation of physical and chemical
phenomena at a few or single-molecule levels. This extreme sensitivity is
possible thanks to the highly confined local field intensity enhancement,
which depends on the geometry of plasmonic nanocavities. Indeed, suitably
designed structures providing engineered local optical fields lead to enhanced
optical sensing based on different phenomena such as surface enhanced Raman
scattering, fluorescence, and Forster resonance energy transfer. Here, I
illustrate our most recent results on plasmonic nanopores, with specific
emphasis on the detection of single molecules.
