Metals like titanium and chromium can damp the LSPR of gold nanoparticles (AuNPs) strongly, due to chemical interface damping [1, 2]. nanoparticle-based localized surface plasmon resonance (LSPR) sensors have been reported to detect biological9,10 and chemical entities.11 Propagating surface plasmons are evanescent electromagnetic waves bounded by flat smooth metal-dielectric interfaces and arise from oscillations of the conduction The double toroidal spoof localized surface plasmons (LSPs) on combined split ring resonators (SRRs) are proposed and experimentally demonstrated at microwave frequencies. Based on conventional printed circuit board techniques on a dielectric substrate, the designed metamaterial clearly shows two toroidal spoof LSP resonances.

Moreover, the LSPR is responsible for the electromagnetic-field enhancement that leads to surface-enhanced Raman scattering (SERS) and other surface-enhanced spectroscopic processes. Localized surface plasmon resonance (LSPR) has emerged as a leader among label-free biosensing techniques in that it offers sensitive, robust, and facile detection. Traditional LSPR-based biosensing utilizes the sensitivity of the plasmon frequency to changes in local index of refraction at the nanoparticle surface. LSPRs (localized surface plasmon resonances) are collective electron charge oscillations in metallic nanoparticles that are excited by light.

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. In this work, we tuned the LSPR peaks of Ag nanotriangles and explored the wavelength-dependent LSPR shift upon the adsorption of some resonant molecules. Localized surface plasmon resonance (LSPR) in semiconductor nanocrystals (NCs) that results in resonant absorption, scattering, and near field enhancement around the NC can be tuned across a wide optical spectral range from visible to far-infrared by synthetically varying doping level, and post synthetically via chemical oxidation and reduction, photochemical control, and electrochemical control.

This review describes recent fundamental spectroscopic NANO REVIEW Open Access Light-emitting diodes enhanced by localized surface plasmon resonance Xuefeng Gu1,2, Teng Qiu1*, Wenjun Zhang3, Paul K Chu3 Abstract Light-emitting diodes [LEDs] are of These nanostructures form the sensitive sensor surface where localized surface plasmons are excited using polarized or unpolarized light emitted by a source of visible-infrared light (l = 400-900 nm). The light is transmitted through the nanostructures, where it can couple to the surface mode and yield localized surface plasmons. Localized surface plasmon resonance (LSPR) uses gold nanoparticles – as opposed to a thin film of gold – to exploit the phenomena of SPR. When broadband white light is shone on the gold nanoparticles, a strong resonance absorbance peak is produced in the visible spectrum of light.
