1. An assay device for detecting the presence or quantity of an analyte residing in an aqueous sample, the device comprising:

  • a non-porous support; and

    at least one flow path along which an aqueous sample can travel, wherein the at least one flow path comprises, on the non-porous support, a non-phase-separated combination of at least one amphipathic polymer and at least one hydrophobic probe, reporter or reagent, wherein, in use, the at least one amphipathic polymer dissolves in the aqueous sample and increases mixing and interaction between the at least one hydrophobic probe, reporter or reagent and the aqueous sample for any degree of water solubility of the at least one probe, reporter or reagent, including water-insolubility, and promotes and/or controls fluid flow along the at least one flow path.
