Surface-enhanced infrared absorption spectroscopy (SEIRA) emerged as a powerful label-free technique for highly sensitive and chemical specific analysis. SEIRA can be realized by employing the nanophotonic planar structures such as metasurfaces that can enhance light-matter interaction in the spectral bands of molecular vibrations.

Abstract Infrared spectroscopy resolves the structure of molecules by detecting their characteristic vibrational fingerprints. Subwavelength light confinement and nanophotonic enhancement have extended the scope of this technique for monolayer studies. However, current approaches still require complex spectroscopic equipment or tunable light sources.
