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. In this paper, we present a phase-intensity surface plasmon resonance (SPR) biosensor and demonstrate its use for avian influenza A (H5N1) antibody biomarker detection. The sensor probes the intensity variation produced by the steep phase response at surface plasmon excitation. The prism sensor head is fixed between a Surface Plasmon Resonance for Biosensing is a very interdisciplinary research playground and this Special Issue will serve as a vehicle for the dissemination of recent research in this exciting area.

This chapter introduces SPWs, presents methods for their excitation and interrogation, and discusses the concept of SPR optical biosensors. Surface plasmon resonance (SPR) biosensors belong to label-free optical biosensing technologies. The SPR method is based on optical measurement of refractive index changes associated with the binding of analyte molecules in a sample to biorecognize molecules immobilized on the SPR sensor. Surface Plasmon Resonance - BiaCore Biosensor SPR is a universal tool for studying and characterizing macromolecular interaction in a label-free state.

The colors exhibited by gold nanoparticles arise from interaction of incident light with the “free” electrons resulting in resonant excitation of an oscillating dipole (surface Plasmon resonance). The color change is only one of the several modalities that have been exploited for design of biosensors. 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.

Biosensors based on surface plasmon resonance (SPR) have shown significant applications in drug screening, environmental monitoring, immunoassay, etc.; however, improving the sensitivity of these biosensors is one of the prime tasks at present.In this study, taking advantage of the special optical and morphological characteristics of MoS 2 nanoflowers, we synthesized a sensitivity-improved SPR
