Angle-scanning SPR imaging for detection of biomolecular interactions on microarrays.


In this paper we describe the use of a commercial surface plasmon resonance (SPR) imaging instrument for monitoring the binding of biomolecules on user-defined regions of interest of a microarray. By monitoring the angle shift of the SPR-dip using a continuous angle-scanning mode instead of monitoring the change in reflectivity at a fixed angle, a linear… (More)
