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”.

The phenomenon is a result of the interactions between the incident light and surface electrons in a conduction band [1] . Localized surface plasmon resonance (LSPR) spectroscopy of metallic nanoparticles is a powerful technique for chemical and biological sensing experiments. Moreover, the LSPR is responsible for the electromagnetic-field enhancement that leads to surface-enhanced Raman scattering (SERS) and other surface-enhanced spectroscopic processes. In this study, we investigated use of local surface plasmon resonance (LSPR) of metal nanoparticles (NPs) as a correlative light and electron microscopy (CLEM) tag for biological samples.
