We report the application of near-infrared surface plasmon spectroscopy to study the sensitive detection of the binding of proteins to functionalized surfaces. Working at 300 nm, where both water and silicon are transparent, the method is of particular interest for biosensors based on silicon technology. We describe the application of thin functionalization layers forming a step on the sensor surface...
