1. A device for detecting a two or more analytes in a sample, said device comprising:

  • a channel having affixed therein a binding partner for each of said two or more analytes, where the binding partners for each of said two or more analytes are located in different regions of said channel prior to sample introduction and said channel has a cross-sectional area small enough such that when analytes are released from said two or more binding partners into a fluid flowing through said channel, said analytes remain spatially segregated until they reach a detection point along said channel downstream from said binding partners; and

    a detector that detects said analytes within said channel at said detection point.
