Long period gratings modified by the deposition of a self-assembled colloid monolayer of gold have been shown to enhance SRI sensitivity, which was attributed to the localized surface plasmon resonance (LSPR) of gold nanoparticles61. The system was used after functionalization of the gold nanoparticles with dini-trophenyl (DNP) antigen, for the detection of anti-(DNP) with a limit of detection as low as 9.5 x 10 10 M. [Pg.71]

The optimal enhancement effect is observed when the localized surface plasmon resonance is tuned to the emission wavelength of a locally situated fluorophore [86]. This is consistent with the model suggesting a greatly increased efficiency for energy transfer from fluorophores to surface plasmons [78]. Since resonance energy transfer is involved, the important factors affecting the intensity of fluorescence emission must also be the orientation of the dye dipole moments relative to the... [Pg.123]

The overall goal of my thesis work is to elucidate the sensing mechanism of the localized surface plasmon resonance (LSPR) of triangular Ag nanoparticle biosensors and to apply that knowledge to optimize their use as a novel analytical tool. [Pg.365]

Surface plasmons, or surface plasmon polaritons, are surface electromagnetic waves that propagate inside a metal along a metal/dielectric (or metal/ vacuum) interface their excitation by light is surface plasmon resonance (SPR) for planar surfaces or localized surface plasmon resonance (LSPR) for nanometer-sized metal particles. [Pg.685]

Metal nanostructures (such as particles and apertures) can permit local resonances in the optical properties. These local resonances are referred to as localized surface plasmons (LSPs). The simplest version of the LSP resonance comes for a spherical nanoparticle, where the electromagnetic phase-retardation can be neglected in the quasi-static approximation, so that the electric field inside the particle is uniform and given by the usual electrostatic solution [3] ...

While it is safe to say that SPR is a mature technique from the historical perspective, new driving forces appear to challenge traditional SPR for various needs that traditional SPR sensors fail to satisfy. In particular, a novel SPR biosensor that attempts to capitalize on the nanotechnology, by which to localize surface plasmons (SPs), has emerged and thus has been appropriately called a localized surface plasmon resonance (LSPR) biosensor. In this chapter, 1 focus on the LSPR biosensor by reviewing its operating principles and properties in a systematic way and venture into future directions along which LSPR biosensors evolve.
