The presently disclosed subject matter provides dyes having an improved photostability, biosensors comprising such dyes, and methods of use thereof, including methods for detecting target molecules in a sample under test and for live-cell imaging. The dyes can include a binding member, including a biomolecule or fragments thereof, which can interact with target molecules of interest and can be specific to a given conformational state or covalent modification, e.g., phosphorylation, of the target molecule. The presently disclosed dyes can be used for detecting changes in the binding, conformational change, or posttranslational modification of the target molecule.
