Abstract:
1. A detection method comprising: providing a sample that is suspected of containing a target biomolecule; providing a multichromophore that comprises a conjugated polymer, wherein said polymer comprises a plurality of low bandgap repeat units sufficient for the polymer to form an excited state when the polymer is contacted with incident light in the region of about 450 nm to about 1000 nm, and wherein said multichromophore has a detectable emission upon excitation and wherein the multichromophore can bind to the target biomolecule; providing a sensor biomolecule capable of selectively binding to the target biomolecule, wherein the sensor is conjugated to a substrate; contacting the substrate with a solution comprising the sample; and detecting whether target biomolecule, if present, has bound to the sensor by applying a light source that can excite the multichromophore and detecting whether light is emitted in the vicinity of the substrate.
