    摘要: The invention provides methods for the detection, quantification, identification and structural analysis of one or more molecules. Mass spectrometry (MS) is not a universal detector as all molecules do not ionize equally well leading to poor signal to quantity information. MS can be optimized to identify the specific mass of a binding component when the presence of a material is known. Colorimetric resonant reflectance optical sensors provide a universal mass detector in that nearly all biological masses give equally proportional signals. The combined methods allow selection and or detection with quantification of all masses binding to the sensor with the ability to identify specific molecules by their individual masses and structure analyses.

    摘要: Performing high-resolution determination of the relative shift of the spectral properties of a biosensor. The shift in the resonance peak of the biosensor is indicative of the amount of material bound to the surface of the biosensor. A preferred biosensor is a Guided Mode Resonant Filter Biosensor (GMRFB). In one aspect of the invention, curve fitting is used to determine the relative location of the spectrum of the unexposed biosensor with respect to those spectra that are altered (e.g., shifted) by the presence of materials bound to the surface of the biosensor. In an alternative embodiment, the cross correlation function is used to detect spectral peak offsets between a reference spectrum and a spectrum measured from an exposed biosensor. In yet another alternative, maximal likelihood estimation techniques are used to determine the spectral shift or offs.
