Surface Plasmon Resonance (SPR) is a phenomenon that occurs at the interface of media with different refractive indices. SPR detects refractive index change
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 glass prism and the subsequent reflection is Surface Plasmon Resonance (SPR) is an optical technique used to measure molecular interactions in real time.SPR can occur when plane-polarized light hits a metal film under total internal reflection conditions. Se hela listan på cleanenergywiki.org In recent years, the local surface plasmon resonance (LSPR) technique has received a lot of attention due to its applications in the sensing of various physical, chemical and biological parameters [1–4]. The deployment of optical fibres as LSPR devices has achieved an outstanding position due to its advan- These nanostructures form the sensitive sensor surface where localized surface plasmons are excited using polarized or unpolarized light emitted by a source of visible-infrared light (l = 400-900 nm). The light is transmitted through the nanostructures, where it can couple to the surface mode and yield localized surface plasmons. Shreyas, Both RF and Wave Optics physics interfaces can be used to solve this problem. There are several papers from Comsol conferences about surface plasmon resonance for both Kretschmann-Raether and Otto configurations – try to search keywords “surface plasmon resonance”. From the plasmon band shift versus the refractive index, ultra-high local surface plasmon resonance sensitivity (413 nm RIU −1 or 1.24 eV RIU −1, figure of merit (FOM) = 4.59) was reached at ∼630 nm, making these materials promising for chemical/biological sensing applications.
