More than 50 papers on surface plasmon resonance biosensors, published between 2016 and mid-2018, are reviewed. Papers concerning the determination of large particles such as vesicles, exosomes, cancer cells, living cells, stem cells, and microRNA are excluded, as these are covered by a very recent review. The reviewed papers are categorized into five groups, depending on the degree of

If mass is bound to the surface within this 300 nm range then it perturbs the plasmon and, for a photon of fixed wavelength, shifts the resonance angle. If the plane of the metal surface is fixed, then the resonance wavelength can be identified by scanning through a range of angles of incidence for the photon and determining the resonance angle (Mullet et al., 1998).

Some applications of gold nanoparticles In this work, the long-range surface plasmon resonance (LRSPR) sensor based on dielectric Ti3C2Tx-graphene layers is demonstrated. Here, MXene (Ti3C2Tx) is used as a metal for strong surface plasmon’s generation at 1550 nm excitation wavelength. Graphene is used to attach the biomolecules having carbon–carbon structure with pi stacking interactions. The detection accuracy (DA) and figure SPIE Digital Library Proceedings.

In this study, we report the development of a nanoparticle-enhanced biosensor by integrating both the nanoparticles and immunoassay sensing technologies into a phase interrogation surface plasmon resonance (SPR) system for detecting antigen at a concentration as low as the femtomolar range.

Therefore, a new biosensor for the direct detection of chlorophene in real water is presented, based on surface plasmon resonance (SPR) and using a laccase enzyme as a recognition element. The biosensor chip was obtained by covalent immobilization of the laccase on a gold-coated surface through carbodiimide esters.

The Surface Plasmon Resonance (SPR) biosensor is a type of biosensor which is very powerful for detecting and determining the specificity, affinity, and kinetic parameters of macromolecular bonds. The working principle of this biosensor uses metals such as gold (Au), silver (Ag), and aluminum (Al) to excite surface plasmon waves which are very sensitive to changes in the refractive index on Mathcad programs demonstrated that only TM waves could be used for surface plasmon resonance on a metal surface in Otto configuration or Kretschman configuration. With Rouard's recursive method to numerically simulate light reflectivity in a multilayered system, we found benchmarks of SPR biosensors, and got linear relationships about the shift of the SPR angle to the surface concentration of biological films.

Surface plasmon resonance (SPR) refers to excited charge density oscillations that exist along the boundary between a metal and a dielectric with permittivities

SPR is the basis of many standard tools for measuring adsorption of material onto planar metal surfaces or onto the surface of metal nanoparticles. It is the fundamental principle behind many color-based biosensor applications, different lab-on-a-chip sensors and diatom photosynthesis. This review aims to highlight the applications of one of the most prominent optical biosensor technologies, surface plasmon resonance (SPR), in the drug discovery process and quality analysis of pharmaceutical compounds and their particularities.

Surface Plasmon Resonance (SPR) is a phenomenon that occurs at the interface of media with different refractive indices. SPR detects refractive index change with high sensitivity. The following article is Open access Development of surface plasmon resonance (SPR) biosensors for use in the diagnostics of malignant and infectious diseases S Firdous3,4,1, S Anwar1,2and R Rafya1 Published 26 April 2018• © 2018 Astro Ltd Surface Plasmon Resonance is a phenomenon that occurs when polarized light hits a metal film at the interface of media with different refractive indices. SPR techniques excite and detect collective oscillations of free electrons (known as surface plasmons) via the Kretschmann configuration, in which light is focused onto a metal film through a Optical Surface plasmon resonance (SPR) biosensors represent the most advanced and developed optical label‐free biosensor technology. Optical SPR biosensors are a powerful detection and analysis tool that has vast applications in environmental protection, biotechnology, medical diagnostics, drug screening, food safety and security.

The sensor probes the intensity variation produced by the steep phase response at surface plasmon excitation.
