Flavonoid compounds that are selective for a protein, a portion or a living cell, or a portion of an organism may be used as biological imaging agents. The flavonoid compounds are useful for methods of imaging organisms such as zebrafish embryos and zebra fish. Flavonoid compounds may also be used to detect protein. Advantageously, flavonoids that selectively bind protein, a portion of a living cell, or a portion of an organism may exhibit a florescence “turn-on” mechanism, where the flavonoids that are selectively bound exhibit a florescence response when excited.

characterized. The flavonoids were nearly non-fluorescent in aqueous environment, but exhibited two emission peaks (one λem at 495–536 nm and the other at 570–587 nm) in organicsolvents, which were assigned to the excited normal (N*) and tautomer (T*) emission. When the dyes were examined on oligodendrocyte cells, they were found to selectively accumulate in the endoplasmic reticulum (ER), a eukaryotic
