“…As a consequence, goldcoated crystals can be considered as bulk substrates for ellipsometry. The additional advantage of metal substrates is that they are compatible with total internal reflection ellipsometry (TIRE) [45], albeit the thicknesses of about 50 nm need to be used. However, the surface roughness in the case of metal substrates can be much larger and less controllable as compared with silicon wafers.…”

“…Surface plasmons are waves of variable electric charge density that can arise and propagate in the electron plasma of a metal along its surface or along a thin metal film. The resonant excitation of such oscillations by an electromagnetic wave in a thin layer of conductive material placed between two media with different refractive indices is called SPR [24]. SPR is a phenomenon of violation of the condition of total internal reflection in which a significant part of the energy of the light incident on the surface of the metal film is converted into the energy of plasmons, as a result of which the intensity of the light reflected from the surface of the metal film drops sharply.…”

In this review, the state of research over the past fifteen years in the field of the applications of metal phthalocyanines and porphyrin derivatives as well as their hybrid materials with carbon nanotubes, metal oxides, and polymers in optical sensors based on the phenomenon of surface plasmon resonance (SPR) is analyzed. The first chapter of the review presents an analysis of works on the use of porphyrins and phthalocyanines in classical SPR sensors for the detection of gases and volatile organic vapors, as well as their improved modifications, such as total internal reflection ellipsometry (TIRE) and magneto-optical SPR (MOSPR) methods, while the second chapter is devoted to their application for the detection of various analytes in solutions. The third chapter of the review summarizes publications describing recent advances in the use of porous materials based on hybrids of carbon nanotubes and oxides with metal phthalocyanines. The fourth chapter describes two-dimensional metal-organic frameworks (MOFs) based on metal porphyrin derivatives as SPR sensitizers.

“…The biocompatibility of dielectric surfaces with biomolecules, immune-sensing and other life science applications make the BSW an attractive tool for optical surface sensing, which can replace the very widely spread use of surface plasmon resonance sensors [5]. Surface plasmon polariton (SPP) optical sensors are still the most popular due to the high sensitivity which can be obtained because of the dielectric permittivity dispersion features of metals and the enhancement of the electric field at the metal/dielectric interfaces [6,7]. In SPP-type optical sensors, a glass prism is commonly used as a coupler to achieve conditions of total internal reflection (TIR) and to excite the propagated SPP waves, which are transverse magnetic (TM) p-polarized.…”

“…This makes possible the monitoring of biomolecule immobilization processes on their surfaces and their interaction with other proteins in opaque media. Moreover, the exploitation of such evanescent surface waves allows one to avoid the propagation of light directly through the liquids, which induces additional signal noises and decreases sensitivity [7]. TIR setups are also used in surface plasmon resonance (SPR) [8] and BSW based biosensors [3].…”

The total internal reflection ellipsometry (TIRE) method was used for the excitation and study of the sensitivity features of surface plasmon polariton (SPP) and Bloch surface waves (BSWs) resonances. For the BSWs generation distributed Bragg gratings were formed on the tops of the substrates (BK7 glass substrate), which had six bilayers of ~120 nm SiO2 and ~40 nm TiO2 and 40 nm of TiO2 on the top. The SPP sample consisted of the BK7 glass prism and a gold layer (45 nm). Numerical calculations of the optical dispersions and the experimental TIRE data have shown that SPP resonance overtake the BSWs in wavelength scanning by a factor of about 17. However, for the ellipsometric parameters Ψ and Δ in the vicinity of excitations, the BSW sensitivity is comparable with SPP. The obtained resolutions were ΔSPP=7.14×10−6RIU, ΨSPP=1.7×10−5RIU for the SPP and ΔBSW=8.7×10−6RIU, ΨBSW=2.7×10−5RIU for the BSW. The capabilities of both surface excitations are discussed from the sensitivity point of view in the design of these advanced biosensors.
