Sample analysis systems and methods are provided. In one embodiment, the method may be achieved by applying a substance to a surface of a substrate having a first binding agent immobilized thereon; removing unbound material from at least a portion of the substrate having the substance applied thereon; applying a second binding agent to the surface of the substrate, wherein the second binding agent is optically labeled or unlabeled; removing unbound material from at least a portion of the substrate having the second binding agent applied thereon; responsive to detecting the optically labeled second binding agent bound to the substance, identifying the analyte present in the sample; and responsive to not detecting the optically labeled second binding agent bound to the substance, determining that the analyte is absent in the sample; wherein the applying the substance or second binding agent to the surface of the substrate steps are concurrent with the respective removing unbound material from at least a portion of the substrate steps. |
