Thioflavin T (ThT, Thioflavine T, Basic Yellow 1) is a benzothiazole dye that exhibits enhanced fluorescence upon binding to amyloid fibrils and is commonly used to diagnose amyloid fibrils. This compound is found to exist as micelles at concentrations commonly used to monitor fibrils by fluorescence assay. The micelles of this chemical bind to amyloid fibrils leading to enhancement of fluorescence emission.
