“…PSPs can be excited on the metallic films which have several approaches as the Kretschman [7] and Otto [8] prism coupler, optical waveguides coupler [9], diffraction gratings [10], and optical fiber coupler [11], whereas LSPs can be excited on metallic nano-particles, which both can induce a strong enhancement of electromagnetic filed in the near-field region (resonance amplification), leading to a extensive application in surface-enhanced Raman scattering (SERS) [12], fluorescence enhancement [13], refractive index (RI) measurement [14], biomolecular interaction detection [15], and so on.…”

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.

Biosensors based on the principle of surface plasmon resonance (SPR) detection were used to measure biomolecular interactions in sarcomeres and changes of the dielectric constant of tubulin samples with varying concentration. At SPR, photons of laser light efficiently excite surface plasmons propagating along a metal (gold) film. This resonance manifests itself as a sharp minimum in the reflection of the incident laser light and occurs at a characteristic angle.The dependence of the SPR angle on the dielectric permittivity of the sample medium adjacent to the gold film allows the monitoring of molecular interactions at the surface. We present results of measurements of cross-bridge attachment/detachment within intact mouse heart muscle sarcomeres and measurements on bovine tubulin molecules pertinent to cytoskeletal signal transduction models.

“…The angle shift is, of course, dependent on molecular concentration as well as the type of the molecules. The physical models usually used for the description of this shift are based mainly on the concept of an additional layer on the surface of SPR-converter, which is characterized by the effective thickness h and refractive index N, analogous to the similar idea of ellipsometry of thin films [1][2][3][4]. Another approach is based on the idea of ultra-thin film representation [5].…”

3-D quantification of biomolecular covers using surface plasmonpolariton resonance experiment Chegel, V.; Chegel, Yu.; Guiver, Michael; Lopatynskyi, A.; Lopatynska, O.; Lozovski, V. Sensors and Actuators B 134 (2008) The concentration of surface molecules N s and components of molecular susceptibility jl (ω) can both be determined from surface plasmon-polariton resonance (SPPR) experiments, instead of effective layer thickness and index of refraction, which are usually determined. The theoretical consideration of a molecular layer as monolayer of separated 3D-oscillators provides a new perspective for investigating molecules during SPPR experiment. It is shown that SPPR response and the form of the reflective curve depend on the form of a biomolecule and its orientation relative to the surface of the metal-carrier of plasmon oscillations. The experimental data for immunological reaction for the calculation of surface molecular concentration and mass of biomolecular covering are presented.
