Fano Metamaterials on Nanopedestals for Plasmon-Enhanced Infrared Spectroscopy
Abstract We here report a sensing platform for surface-enhanced infrared absorption (SEIRA) spectroscopy, based on Fano metamaterials (FMMs) on dielectric nanopedestals.FMMs consist of two parallel gold (Au) nanorod antennas, with a small horizontal coupler attached to one of the nanorod antenna.When placed on SiO2 dielectric nanopedestals, which e
