“…In both cases, surface plasmon resonance is achieved at specific angle of incidence. The excitation of SPs results in a drop of the intensity of the reflected light [2] and a sharp phase transition [4,5] at the resonance angle [6] or wavelength [7]. This resonance is sensitive to the properties of the dielectric layer adjacent to the metal as well as the metal surface.…”

Abstract: This paper describes theoretical and experimental study of the fundamentals of using surface plasmon resonance (SPR) for label-free detection of voltage. Plasmonic voltage sensing relies on the capacitive properties of metal-electrolyte interface that are governed by electrostatic interactions between charge carriers in both phases. Externally-applied voltage leads to changes in the free electron density in the surface of the metal, shifting the SPR position. The study shows the effects of the applied voltage on the shape of the SPR curve. It also provides a comparison between the theoretical and experimental response to the applied voltage. The response is presented in a universal term that can be used to assess the voltage sensitivity of different SPR instruments. Finally, it demonstrates the capacity of the SPR system in resolving dynamic voltage signals; a detection limit of 10mV with a temporal resolution of 5ms is achievable. These findings pave the way for the use of SPR systems in the detection of electrical activity of biological cells. 56, 1495-1503 (2013). 34. R. Azzam and N.

“…Detection of IgG was also enhanced by approximately the same factor [23]. The excitation of the SP on microhole arrays with a Dove prism SPR [24] led to a refractive index resolution of 1.5×10 −6 RIU, equivalent to thin film SPR sensors; the comparison was performed on the same instrumentation [23]. The slightly worse noise level observed for microhole arrays is explained by the asymmetry of the peak for this plasmonic substrate, which is very similar to the peak shape simulated for nanograting, as predicted by Alleyne et al [18].…”

“…Chemometric data analysis, for example principlecomponent analysis, must be validated to capture changes in the spectra and contribute to denoising the data. For example, a pre-processing step involving singular value decomposition and reconstitution of the data with the very first components reduced the noise level of SPR data by one order of magnitude [24]. Harnessing the full power of chemometric data analysis will be essential to further reduce the noise in SPR data and to improve detection limits of SPR sensing.…”

Surface plasmon resonance (SPR) biosensing has matured into a valuable analytical technique for measurements related to biomolecules, environmental contaminants, and the food industry. Contemporary SPR instruments are mainly suitable for laboratory-based measurements. However, several point-of-measurement applications would benefit from simple, small, portable and inexpensive sensors to assess the health condition of a patient, potential environmental contamination, or food safety issues. This Trend article explores nanostructured substrates for improving the sensitivity of classical SPR instruments and nanoparticle (NP)-based colorimetric substrates that may provide a solution to the development of point-of-measurement SPR techniques. Novel nanomaterials and methodology capable of enhancing the sensitivity of classical SPR sensors are destined to improve the limits of detection of miniature SPR instruments to the level required for most applications. In a different approach, paper or substrate-based SPR assays based on NPs, are a highly promising topic of research that may facilitate the widespread use of a novel class of miniature and portable SPR instruments.

This paper reviews the primary literature reporting the use of ionic liquids (ILs) in optical sensing technologies. The optical chemical sensors that have been developed with the assistance of ILs are classified according to the type of resultant material. Key aspects of applying ILs in such sensors are revealed and discussed. They include using ILs as solvents for the synthesis of sensor matrix materials; additives in polymer matrices; matrix materials; modifiers of the surfaces; and multifunctional sensor components. The operational principles, design, texture, and analytical characteristics of the offered sensors for determining CO2, O2, metal ions, CN -, and various organic compounds are critically discussed. The key advantages and disadvantages of using ILs in optical sensing technologies are defined. Finally, the applicability of the described materials for chemical analysis is evaluated, and possibilities for their further modernization are outlined.
