plasmon resonance (LSPR). Overview of Localized Surface Plasmon Resonance Localized surface plasmon resonance is generated by metal nanoparticles, typically gold and silver. LSPR produces a strong resonance peak in the visible range of light, with its position being highly sensitive to the local refractive index surrounding the particle. Using The integration of silver and gold nanoparticles with graphene is frequently sought for the realization of hybrid materials with superior optical, photoelectric and photocatalytic performances. A crucial aspect for these applications is how the surface plasmon resonance of metal nanoparticles is modified aft This video explains what Surface Plasmon Resonance technology is, how it is used to detect small molecules and their interaction with other proteins.For more The impact of different gold nanoparticle (GNP) structures on plasmonic enhancement for DNA detection is investigated on a few-layer graphene (FLG) surface plasmon resonance (SPR) sensor. Two distinct structures of gold nano-urchins (GNu) and gold nanorods (GNr) were used to bind the uniquely designed single-stranded probe DNA (ssDNA) of Mycobacterium tuberculosis complex DNA. It is essential to develop a simple and sensitive method to rapidly detect residual fungicides in agricultural products to protect human health. So far, little studies have been reported on potential application of gold nanospheres (AuNSps) as a surface plasmon resonance based sensor for in-situ detection of residual fungicides.
Plasmon Resonance Energy Transfer occurs when nanoparticles are connected to molecular chromophores (an atom or molecule whose presence is responsible for the color of the compound), then the plasmon resonance energy can be transferred to the molcular chromophore. Here, we consider gold as plasmonic material as the external coating for exciting the surface plasmon to detect the refractive index of the external analyte sensing to facilitate the practical Gold Nanoparticle-Functionalized Surface Plasmon Resonance Optical Fiber Biosensor: In Situ Detection of Thrombin With 1 n·M Detection Limit Abstract: We present an optical fiber biosensor that employs both long-range and localized surface plasmon resonances (SPRs) to sensitively detect very small changes in the resonances due to the surrounding refractive index. However, as plasmons are confined to the plane of the gold film, for SPR it is only the vector component parallel to the surface that matters. Thus, the energy and the angle of incident light must match to create surface plasmon resonance. A highly sensitive surface plasmon resonance-based PCF biosensor is explored in this research work. Outside the fiber frame, active plasmonic material gold (Au) with a thickness of 25 nm has been deposited which is chemically steady and is the primary sensing layer of the presented sensor.

In this paper a refractive index sensor based on localized surface plasmon resonance (LSPR) in a Plastic Optical Fiber (POF), is presented and experimentally tested. LSPR is achieved exploiting five-branched gold nanostars (GNS) obtained using Triton X-100 in a seed-growth synthesis. They have the uncommon feature of three localized surface plasmon resonances. The strongest LSPRs fall in two
