What is Surface Plasmon Resonance?
Surface Plasmon Resonance, SPR, is a physical phenomenon that occurs when (polarized) light hits a metal film at the interface of media with different refractive indices. Surface plasmons are collective oscillations of free electrons and these can be excited by...
Multiplex SPR
With multiplex SPR, a large surface area (~1 cm²) of the SPR sensor can be imaged using a camera. Using array spotting technology, an array of multiple protein spots can be deposited within the defined area. Hundreds of spots can potentially be created in this manner....
SPR and vaccine R&D – Elucidating Binding Mechanisms
One of the first steps in understanding a virus’ mode of action is to understand how it infects host cells. Apart from its RNA or DNA, a virus will have a more or less complex envelope that on one hand acts as a carrier for the nucleic acids and on the other hand...
