1. An amplification device, comprising:

  • a pi-conjugated polymer having an energy migration pathway that transports an excitation energy of the polymer upon exposure of the polymer to electromagnetic radiation, and a chromophore covalently attached to the polymer and in electronic communication with the energy migration pathway, wherein the chromophore emits an emission of radiation greater than that emitted from an essentially identical chromophore associated with a polymer that is free of an energy migration pathway, under essentially identical conditions;

    a source of energy applicable to the polymer to cause the emission of radiation; and

    a detector positioned to detect the emission of radiation,wherein a luminescence characteristic of the chromophore is changed upon interaction of the polymer and/or chromophore with an analyte molecule.
