Surface Plasmon Resonance Sensors: A Materials Guide to

Improving the instrumental resolution of sensors based on localized

Abstract. Abstract 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. One of the most explored characteristics of the noble metal nanoparticles (essentially silver, gold or copper) is the localized surface plasmon resonance (LSPR), which is the frequency at which conduction electrons collectively oscillate in response to the alternating electric field of an incident electromagnetic radiation. 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. 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.

The ability to resolve minute shifts/extinction changes is Localized surface plasmon resonance (LSPR) is shown to be effective in trapping light for enhanced light absorption and hence performance in photonic and optoelectronic devices. Implementation of LSPR in all‐inorganic perovskite nanocrystals (PNCs) is particularly important considering their unique advantages in optoelectronics. Localized surface plasmon resonance (LSPR) sensors serve as sensitive analytical tools based on refractive index changes, which can be applied to affinity-based chemical sensing and biosensing. However, to select the monitoring wavelength, monodisperse Au or Ag nanoparticles must be synthesized.

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.

Nowadays, one of the most extensively exploited features of metallic NPs is the localized surface plasmon resonance (LSPR), which refers to the collective oscillation of electrons on the metallic Localized surface plasmon resonance biosensor integrated with microfluidic chip. Huang C (1), Bonroy K, Reekmans G, Laureyn W, Verhaegen K, De Vlaminck I, Lagae L, Borghs G. A sensitive and low-cost microfluidic integrated biosensor is developed based on the localized surface plasmon resonance (LSPR) properties of gold nanoparticles, which allows label-free monitoring of biomolecular interactions in real-time.

The intensity of UC emission in lanthanide-doped nanomaterials can be estimated by Eq. 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. 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.
