Abstract: Amine functionalized colorimetric resonant biosensor for binding proteins, peptides, DNAs, cells, small molecules, and other chemical or biological molecules that are of interests in the areas of proteomic, genomic, pharmaceutical, drug discovery, and diagnostic studies. The invention relates to a coating process that provides a high density of active amine binding sites on the grating surface of the colorimetric resonant biosensor. The method uses chemical reagents that do not alter or degrade a plastic biosensor structure. The invention further provides for test methods that verify the presence of amine moieties on the activated surface on the colorimetric resonant biosensor.

Abstract: The invention provides compositions and methods for the detection, identification, and quantification of microorganisms, cells, or protein mixtures in a sample.
