Abstract

The present invention relates to a method for production of an improved sensor surface for an SPR instrument, comprising forming a self assembled monolayer (SAM) on a surface and attaching ligands and protein resistant groups, preferably polyethylene glycol (PEG), directly to functional groups on said surface. The invention also relates to a sensor surface produced by these methods use thereof in SPR (surface plasmon resonance) assays or interactions.
