TLDR
A variety of configurations and formats have been devised to exploit the phenomenon of surface plasmon on metal dielectric interfaces for sensing a variety of significant analytes, such as pesticides and explosives, pathogens and toxins, and diseased tissue as discussed by the authors.Abstract:
A variety of configurations and formats have been devised to exploit the phenomenon of surface plasmon on metal dielectric interfaces for sensing a variety of significant analytes, such as pesticides and explosives, pathogens and toxins, and diseased tissue. Researchers continue to aim at detecting lower concentrations in smaller volumes of samples in real time. A new research field, called nanoplasmnonics, has emerged in this regard.read more

Range extension of surface plasmons by dielectric layers.
F Y Kou,Theodor Tamir +1 more
TL;DR: The propagation range of surface plasmons in thin-metal-film geometries can be considerably increased if a suitable dielectric layer is placed in parallel to the film, and the results show that this range extension depends strongly on the separation between the metal film and the dielectrics.
