Review of surface plasmon resonance and localized surface plasmon resonance sensor

Abstract

An overview of recent researches of surface plasmon resonance (SPR) sensing technology in Laboratory of Science and Technology of Micro-Nano Optics (LMNO), University of Science and Technology of China, is presented. Some novel SPR sensors, such as sensors based on metallic grating, metal-insulator-metal (MIM) nanoring and optical fiber, are designed or fabricated and tested. The sensor based on localized surface plasmon resonance (LSPR) of metallic nanoparticles is also be summarized. Because of the coupling of propagating surface plasmons and localized surface plasmons, the localized electromagnetic field is extremely enhanced, which is applied to surface-enhanced Raman scattering (SERS) and fluorenscence enhancement. Future prospects of SPR and/or LSPR sensing developments and applications are also discussed.

Vertically coupled plasmonic slot waveguide cavity for localized biosensing applications

“…We expect our proposed device to be able to detect fluctuations of refractive index induced by a couple of molecules only. Similar results were obtained by localized surface plasmon resonance (LSPR) supported by metallic nanoparticles [6,7] which reveals that for small molecule detection, LSPR can excel SPR because it is more sensitive to changes in refractive index close to its surface [8]. LSPR generally provides smaller bulk sensitivity values compared to SPR but the small detection volume of the LSPR enables an easier differentiation between bulk and surface refractive index changes and thus promotes a better detection of small molecules with a reduced noise from the bulk [9].…”

Recent advances in plasmonic nanostructures for sensing: a review

“…7). 100,101 This change in transmitted light properties (i.e., intensity, wavelength, or angle) allows for the noninvasive detection of chemical or biochemical species of interest. In addition, by modifying the plasmonic surface with receptors, specific and sensitive SPR sensors can be fabricated.…”

Modeling of all-optical even and odd parity generator circuits using metal-insulator-metal plasmonic waveguides

“…Despite the deep subwavelength confinement of surface plasmon polaritons (SPPs) with respect to other nanophotonic waveguides such as photonic crystals, SPP waveguides work well beyond the diffraction limit [2][3][4]. Plasmonics is one of the promising fields of integrated photonics due to its numerous applications in optical clocking, cancer therapy, nano-lithography, solar cells, etc.…”
