Methods are provided for analyzing and identifying one or more binding partners using a colorimetric resonant optical biosensor, wherein the biosensor comprises a two-dimensional grating or a linear grating, a substrate that supports the grating, specific binding substances immobilized on the surface of the biosensor, to immobilize the one or more binding partners and, after elution of the one or more binding partners, mass spectrometry analysis to analyze and identify the one or more binding partners. |
