Fluorescence quenching of elsinochrome-A in presence of Formamide

Fluorescence quenching of elsinochrome-A in presence of formamide is reported here. It was found that the quenching observed was of static nature. It is also observed that quenching of the fluorescence of the indicator had a full reversibility. As it has a full reversibility and high sensitivity, a novel optical sensor for formamide can be constructed on this quenching.
