Surf ace Plasmon Resonance in Thin Gold Films Martin Magnuson Laboratory of Applied Physics, Linkoping Institute of Technology, S-581 83 Linkoping, May 1993 Abstract Surface plasmon resonance (SPR) is an optical technique that can be used for biosensing. The present work accounts for calculations and These resonant oscillations are known as surface plasmons. For small (~30nm) monodisperse gold nanoparticles, the surface plasmon resonance phenomenon causes an absorption of light in the blue-green portion of the spectrum (~450 nm) while red light (~700 nm) is reflected, yielding a rich red color.

Multi-parametric surface plasmon resonance can be used not only to measure molecular interactions but also nanolayer properties or structural changes in the adsorbed molecules, polymer layers or graphene, for instance. We study the potentialities of a two-color Surface Plasmon Resonance (SPR) spectroscopy nanosizer by monitoring the assembling of a colloidal dispersion of citrate stabilized gold nanoparticles (AuNPs) on SiO2 surface. When the AuNPs/water composite’s optical density layer is negligible and the electron mean-free path limitation is taken into account in the AuNPs’ dielectric constant;s 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 Keywords: plasmon resonance, gold nanoparticles, Mie theory, plasmon sensing, SERS, near-field enhancement S Supplementary material for this article is available online (Some figures may appear in colour only in the online journal) Topical Review IOP Contents 2021-04-04 2012-01-17 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.
