Surface plasmon resonance (SPR) is the most common label-free technique for the measurement of biomolecular interactions. SPR instruments measure the change in the refractive index of light reflected from a metal surface (the "biosensor"). Binding of biomolecules to the other side of this surface leads to a change in the refractive index which is proportional to the mass added to the sensor surface.
