Surface-enhanced Raman scattering (SERS) has become a powerful tool in chemical,
material and life sciences, owing to its intrinsic features (ie, fingerprint recognition …

Recently, a large number of experimental and theoretical works have revealed a variety of
plasmonic nanostructures with the capabilities of Fano resonance (FR) generation. Among …

Plasmonic clusters can support Fano resonances, where the line shape characteristics are
controlled by cluster geometry. Here we show that clusters with a hemicircular central disk …

We provide a review of the main aspects related to surface-enhanced Raman scattering
(SERS) enhancement factors (EFs), from their origins to the important issue of their practical …

Strategies for in-liquid molecular detection via Surface Enhanced Raman Scattering (SERS)
are currently based on chemically-driven aggregation or optical trapping of metal …

We report on the near-field coupling of individual gold nanoantennas arranged in tip-to-tip
dimer configuration, leading to strong electromagnetic field enhancements in the infrared …

In this article we show that linear nanoantennas can be used as shared substrates for
surface-enhanced Raman and infrared spectroscopy (SERS and SEIRS, respectively). This …

We report that plasmonic nanoantennas made by DNA origami can be used as reliable and
efficient probes for surface-enhanced Raman spectroscopy (SERS). The nanoantenna is …

Light scattering at nanoparticles and molecules can be dramatically enhanced in the'hot
spots' of optical antennas, where the incident light is highly concentrated. Although this effect …

The optical response of plasmonic nanogaps is challenging to address when the separation
between the two nanoparticles forming the gap is reduced to a few nanometers or even …
