Fabrication of plasmonic nanoantennas by femtosecond direct laser writing lithography - effects of near field coupling on SEIRA enhancement

Infrared (IR) spectroscopy is a label-free and non-destructive method to identify and quantify molecular species based on their material specific IR absorption. Additionally, these characteristic vibrations, also known as infrared fingerprint, can be used to obtain information on the molecular configuration. It is therefore a well-established characterisation technique in physics, life science, and chemistry.
