TL;DR: In this paper, the plasmon resonance of nanostructured graphene was dynamically tuned to selectively probe the protein at different frequencies and extract its complex refractive index, and the extreme spatial light confinement in graphene produced an unprecedented high overlap with nanometric biomolecules, enabling superior sensitivity in the detection of their refractive indices and vibrational fingerprints.

TL;DR: In this paper, an infrared plasmonic surface based on a Fano-resonant asymmetric metamaterial exhibiting sharp resonances caused by the interference between subradiant and super-radiant resonances was introduced.

TL;DR: An imaging-based nanophotonic technique can resolve absorption fingerprints without the need for spectrometry, frequency scanning, or moving mechanical parts, thereby paving the way toward sensitive and versatile miniaturized mid-infrared spectroscopy devices.

TL;DR: In this paper, a photonic crystal nanocavity laser with response times as short as a few picoseconds resulting from 75-fold spontaneous emission rate enhancement in the cavity was demonstrated.

TL;DR: A new tool based on collective excitation of plasmonic nanoantenna arrays is developed and direct detection of vibrational signatures of single protein monolayers is demonstrated and an advanced model based on nonequilibrium Green's function formalism is introduced.
