Abstract
The invention described in detail herein relates to the detection, determination, and quantitation of certain ions and small molecules in solution. The invention specifically relates to improvements in the area of photoluminescent sensors for use in a detection scheme involving the alteration of a photoluminescent label or moiety attached to or associated with an analyte binding macromolecule. One may use the changes in photoluminescence lifetime, changes in ratios of photoluminescence intensity or changes in photoluminescence polarization (anisotropy) to determine the analyte. The photoluminescence change measured correlates to the concentration of the ion or molecule in solution.
