Giant mid-IR resonant coupling to molecular vibrations in sub-nm gaps of plasmonic multilayer metafilms

Short-range ordered plasmonic superlattices of Au nanoparticles have tunable infrared collective plasmon-polariton resonances. The enhanced molecule-plasmon interaction approaches the vibrational strong coupling regime, enabling molecular sensing through giant infrared absorption.
