“…1 To date, the SPP-wave phenomenon has been exploited to sense nearly one thousand biological, chemical, and biochemical analytes with high sensitivity. 2,3 Experimentally, the SPP wave is guided by the interface of a thin metal film and an isotropic dielectric material with both materials taken to isotropic and homogeneous. 1,2 An associated drawback is that only one SPP-wave mode can be guided by the metal/dielectric interface at a specific free-space wavelength when the dielectric material is homogeneous.…”

Multiple surface-plasmon-polariton (SPP) waves can be guided by the interface of a metal and a chiral sculptured thin film (STF). It is possible to embed within the chiral STF a layer of silver nanoparticles as sites to bind recognition molecules for sensing analytes of a certain kind. Chiral STFs were deposited on aluminum thin films. 5-nm-thick layers of silver nanoparticles were deposited in the chiral STF at different depths in different samples. The samples were then deployed in the Turbadar-Kretschmann-Raether configuration to observe the effects the silver-nanoparticle layer had on the multiple SPP-wave modes in relation to the depth. We concluded that the silver-nanoparticle layer tends to shift the angular locations of the SPP-wave modes but does not necessarily affect the location of the SPP-wave modes to an extent that would render the data uninterpretable.

“…The surface plasmon-polariton (SPP) wave has dominated research on electromagnetic surface waves for several decades due to the simple and easy way of exciting it in academic, research, and industrial settings for optical-sensing purposes [1]. To date, the SPP-wave phenomenon has been exploited to sense hundreds of biological, chemical, and biochemical analytes with high sensitivity [2][3][4][5][6][7].…”

“…The sensitivity was calculated in order to estimate the fabricated SMPRI chip's capabilities as follows. Let θ(n inf il , m) denote the angle of incidence for a reflectance dip indicating the excitation of the SPP-wave mode labeled m ∈ [1,2] in Fig. 6a, when n inf il is the refractive index of the infiltrant fluid (which could be air, water, or an aqueous solution of sucrose, in this section).…”

Multiple surface-plasmon-polariton (SPP) waves at a single free-space wavelength can be guided by the interface of a metal and a chiral sculptured thin film (STF). Multilayers comprising a chiral STF of lanthanum fluoride deposited on an aluminum thin film deposited on a glass substrate were fabricated. In some chips, a 5-nm-thick layer of silver nanoparticles was deposited at one of two selected depths in the chiral STF. The chips were then deployed in a prism-coupled configuration in a custom-built machine for surface multiplasmonic resonance imaging (SMPRI), in order to observe the effects the silver-nanoparticle layer on the multiple SPP-wave modes. The angular locations of the SPP-wave modes were found to be not greatly dependent on whether the silver-nanoparticle layer was deposited after the first or the second period of a three-periods-thick chiral STF. With aqueous solutions of sucrose as infiltrant fluids, the angular shifts of the SPP-wave modes were determined as the refractive index of the infiltrant fluid increased. The use of a charge-coupled devices (CCD) camera and upgraded motion-control equipment for SMPRI was found to increase the sensitivity of the chip. The silver-nanoparticle layer was also found to enhance the sensitivity.

“…This method is based on the energy transfer from an optical beam to a surface evanescent wave propagating parallel to a metal/dielectric interface, and this coupling is very sensitive to a local change of the refractive index of the dielectric medium, induced for example by the surface hybridization of biomolecules. One of the ways to realize the SPR sensor array is to measure variations of the reflection coefficient at some fixed wavelength and angle of incidence on 2D surface by using CCD camera [18].…”

Abstract. This work is devoted to development of a multi-element gas sensor based on surface plasmon resonance (SPR) to recognize some alcohols. As sensitive layers capable to change their optical properties when interacting with volatile alcohol molecules, we investigated bulk-porous sorbents -calixarenes (tret-butyl-calix[4,6,8]. Each calixarene was studied to obtain its kinetic concentration SPR characteristics for interaction with ethanol, isopropanol and penthanol vapors. To realize SPR measurements, the sensitive calixarene films (d ∼ 100 nm) were deposited on a gold film (d ∼ 45 nm) by using the method of thermal evaporation in vacuum. Experimental multi-element SPR device was designed as based on the analysis of TV image obtained for the studied array of calixarene films and tested using saturated ethanol vapors. .
