Our company offers the wide range of a high quality Au coated glass plates for SPR or another biochemical Surface plasmon resonance (SPR) is used to measure binding events between molecules ranging from ions to viruses. 1 Current technology provides molecular binding with information on kinetics, affinity and very sensitive concentration measurements, with key applications in surface-enhance spectroscopy and sensing. 4 The SPR is related to the physical process that involves electromagnetic waves Surface Plasmon Resonance (SPR) is a physical process that can occur when plane-polarized light hits a thin metal film under total internal reflection conditions . Total internal reflection When a light beam hits a half circular prism, the light is bent towards the plane of interface, when it is passing from a denser medium to a less dense one. Noble metal nanoparticle-based localized surface plasmon resonance (LSPR) is an advanced and powerful label-free biosensing technique which is well-known for its high sensitivity to the surrounding refractive index change in the local environment caused by the biomolecular interactions around the sensing area.

Se hela listan på 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.

Ulrich's thesis, A local co-operating group (LSG) at IFM monitors and deals with  Localized surface-plasmon resonance (LSPR) refers to the collective oscillation of electrons at the interface of metallic structures, which could be produced through the electron-magnetic interaction of the metal with incident light of a specific wavelength (Haes and Van Duyne, 2002; McFarland and Van Duyne, 2003; Hutter and Fendler, 2004). The intensity of UC emission in lanthanide-doped nanomaterials can be estimated by Eq. Surface plasmon resonance can also be tuned based on the shape of the nanoparticle. The plasmon frequency can be related to the metal dielectric constant.
