resonance takes place through the two gold nanowires embedded symmetrically across the core.
The problem when you switch from light waves to surface plasmons
, though, is that plasmons
very quickly lose their power - they move real fast, but tend to peter out long before they reach their destination.
Plasmonics is an emerging field, but it has its limitations due to the loss of energy in the metal layers, which dissipate the plasmon
energy into heat.
The propagation constant of the surface plasmons
confined to the interface of a semi-infinite dielectric and a semi-infinite metal can be expressed as
resonance (SPR) has been exploited primarily in the area of sensing due to the level of sensitivity and selectivity that the technique offers.
The Plasmogram is intrinsically a device viewed in transmission because surface plasmons
work in transmission mode.
We discuss a recent advance in optical transduction that capitalizes on plasmons
and man-made nanomaterials, which can come together to create a sensitivity so improved that "we can potentially see the binding of a single molecule," says Andrei Kabashin, CNRS Research Director at Aix-Marseille University and lead researcher on the work.

In this work we present a systematic study of surface-localized plasmons
coupling in systems of two metallic nanoparticles following shape, size and distance between them.
