Abstract

A new technology that enables the highly selective and sensitive detection of silver ions has been developed. The method takes advantage of the unique fluorescence property of a mismatched pyrrolo-dC (PdC)-modified duplex DNA, which serves as the key detection component, and the specific interaction of this duplex with silver ions.
