Plasmonic nanoparticles act in this case as transducers that convert changes in the local refractive index into spectral shifts of the localized surface plasmon resonance (LSPR) band. This LSPR-shift assay is a general technique for measuring binding affinities and rates from any molecule that induces a change in the local refractive index around the metallic nanostructures.

This book introduces the fundamentals and applications of the localized surface plasmon resonance (LSPR) property of noble metallic nanoparticles, with an emphasis on the biosensing applications of plasmonic nanoparticles, especially in living cell imaging and photothermal therapy. This resonance is called a localized surface Plasmon resonance or in short localized Plasmon resonance. It is concluded that these modes arise naturally from scattering problem of the small, 2017-10-15 · 1. Food Chem.

Two toroidal spoof LSP resonances are excited due to the conductive A tapered fiber localized surface plasmon resonance (LSPR) sensor is demonstrated for refractive index sensing and label-free biochemical detection. The sensing strategy relies on the interrogation of the transmission intensity change due to the evanescent field absorption of immobilized gold nanoparticles on the tapered fiber surface. Localized surface plasmon resonance (LSPR) is one of the signature optical properties of noble metal nanoparticles. Since the LSPR wavelength ॕ max is extremely sensitive to the local environment, it allows us to develop nanoparticle-based LSPR chemical and biological sensors.

Photocatalytic properties of inorganic composites and their

LSPRs (localized surface plasmon resonances) are collective electron charge oscillations in metallic nanoparticles that are excited by light. They exhibit enhanced near-field amplitude at the resonance wavelength. Localized surface plasmon resonance (LSPR) is one of the signature optical properties of noble metal nanoparticles. Since the LSPR wavelength λ max is extremely sensitive to the local environment, it allows us to develop nanoparticle-based LSPR chemical and biological sensors.
