Localized surface plasmon resonance (LSPR) is an optical phenomena generated by a light wave trapped within conductive nanoparticles (NPs) smaller than the wavelength of light. The phenomenon is a result of the interactions between the incident light and surface electrons in a conduction band [1] .

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. 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.

To enable continuous and dynamic inflammatory biomarker detection, we utilized localized surface plasmon resonance (LSPR) to perform label-free molecule sensing. Since the LSPR sensing mechanism requires only a small sensing area with simplified optical setup, it can be easily integrated with a microfluidic device. In this paper a refractive index sensor based on localized surface plasmon resonance (LSPR) in a Plastic Optical Fiber (POF), is presented and experimentally tested. LSPR is achieved exploiting five-branched gold nanostars (GNS) obtained using Triton X-100 in a seed-growth synthesis.

When the electron cloud is displaced relative to its original position, a restoring force arises from Coulombic attraction between 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. They exhibit enhanced near-field amplitude at the resonance wavelength.

Localized surface plasmon resonances (LSPRs) of silver nanoparticles (AgNPs) exhibit strong UV-visible absorption. The LSPRs can be tuned by fabrication techniques, or by functionalization, and they are sensitive to the nanoparticles’ environment.

Localized surface plasmon resonance (LSPR) occurring in noble metal nanoparticles (e.g., Au) is a widely used phenomenon to report molecular interactions. Traditional LSPR sensors typically monitor shifts in the peak position or extinction in response to local refractive index changes in the close vicinity of the nanoparticle surface. The ability to resolve minute shifts/extinction changes is Localized surface plasmon resonance (LSPR) is one of the signature optical properties of noble metal nanoparticles.
