C Phys. D Phys. Surface plasmon polaritons SPPs are introduced as a waveguide mode at a single interface. It is shown how SPPs in nanostructures can both concentrate the local field intensity and shorten the optical wavelength. Localised surface plasmons LSPs are introduced and described using the quasi-static approximation. It is shown how LSPs lead to local field enhancement, which may be further cascaded to achieve additional enhancement.
A brief discussion of six application areas of surface plasmon nanophotonics is given: surface plasmon resonance SPR sensing, SERS, enhanced fluorescence, nonlinear optics, nanolithography and sub-wavelength imaging, and optical trapping. Article :. Nanophotonics and plasmonics is the study of light at the nanometre-scale. Light can only be focused to a spot roughly half its wavelength in size a few hundred nanometres for visible light.
This limit can be surpassed by coupling light to electrons at the surface of a metal and creating surface plasmons. Research 20 September Open Access. Research 18 September Open Access.

Research 13 September Open Access. Current particle manipulation techniques using light are limited by optical effects, such as diffraction, or lack of dynamic capabilities. The authors report a strategy that combines conventional optical traps with plasmonic tweezers to gain maneuverability of the trapped particles while maintaining plasmonic trap efficiencies.
