1. A polynucleotide sensing solution comprising:
- a signaling chromophore; and
a polycationic multichromophore that is capable of transferring energy to the signaling chromophore upon excitation when brought into proximity thereto, wherein a greater amount of energy can be produced from the signaling chromophore in the presence of the polynucleotide being sensed when the multichromophore is excited.

Abstract
Methods, compositions and articles of manufacture for assaying a sample for a target polynucleotide are provided. A sample suspected of containing the target polynucleotide is contacted with a polycationic multichromophore and a sensor polynucleotide complementary to the target polynucleotide. The sensor polynucleotide comprises a signaling chromophore to receive energy from the excited multichromophore and increase emission in the presence of the target polynucleotide. The methods can be used in multiplex form. Kits comprising reagents for performing such methods are also provided.

17. A sensing complex comprising:
-
a sensor polynucleotide that is single-stranded and is complementary to a target polynucleotide, said sensor polynucleotide attached to a signaling chromophore; and
a polycationic multichromophore complexed with the sensor polynucleotide, wherein the polycationic multichromophore is capable of transferring energy to the signaling chromophore upon excitation when in proximity thereto, wherein the complex can emit light from the signaling chromophore upon excitation of the multichromophore in the absence of target polynucleotide, and wherein a greater amount of emitted light is produced from the signaling chromophore upon excitation of the multichromophore in the presence of target polynucleotide.
