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. 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.

Surface Plasmon Resonance Based Sensors: 4: Homola, Jir

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. Among the reported optical biosensors, surface plasmon resonance (SPR) biosensors show a number of significant advantages over more conventional biosensors, including real-time sensing, label-free detection, fast response and ultra-high refractive index sensitivity. 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.
