Abstract
Plasmonic nanoantennas confine electromagnetic fields at infrared wavelengths to volumes of only a few cubic nanometers, resulting in huge local fields in the vicinity of the resonantly excited metal particles. We exploited these fields to enhance the infrared vibrational bands of molecular monolayers with ultra-high sensitivity.
