Localized surface plasmon resonance (LSPR) spectroscopy of metallic nanoparticles is a powerful technique for chemical and biological sensing experiments. Moreover, the LSPR is responsible for the electromagnetic-field enhancement that leads to surface-enhanced Raman scattering (SERS) and other surface-enhanced spectroscopic processes. 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.

PHYSICAL REVIEW B 91, 115431 (2015) It is difficult to estimate the effect of this approximation, or the effect of nonadiabatic exchange-correlation effects exactly. However, there is much evidence from historical work that already the random phase approximation (pure Coulomb Based on Insplorion’s proprietary optical technology, Nanoplasmonic Sensing (NPS), these robust instruments utilize the optical phenomenon known as Localized Surface Plasmon Resonance (LSPR) and offer sub-second temporal resolution with ultra-sensitivity for both liquid- and gas-phase measurements. 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.
