Curcumin as an amyloid-indicator dye in E. coli

Chem Commun (Camb). 2013 May 14;49(39):4193-5. doi: 10.1039/c2cc37792f. Epub 2013 Jan 4.

Abstract

We have demonstrated that curcumin is an amyloid-specific dye in E. coli. Curcumin binds to curliated whole cells and to isolated curli amyloid fibers. Similar to Congo red, curcumin exhibits a red-shift in absorbance and a significant increase in fluorescence upon binding to isolated curli.
