Abstract
A waveguide-based sensor is disclosed that uses one or more grating patterns of a bioreceptor on a surface of the waveguide to provide a wavelength-specific sensor response without the requirement of labeling the target molecule or the bioreceptor. Furthermore, there is provided a biosensor that, at least to a first order, is insensitive to non-specific binding.
