Abstract
The present disclosure provides methods and lateral flow devices for detecting a plurality of target analytes in a liquid sample. In some implementations, the disclosed lateral flow device comprises a housing unit, a capillary flow bed, a sample-receiving zone, a buffer-receiving zone, and a capture zone. The device is configured to control the flow of the sample and reagent buffer in a sequential manner with minimal mixing. In some implementations, the disclosed method is capable of detecting a plurality of target analytes in an assay by applying the binding agents and the signaling agents in separate or sequential steps.
