Abstract

A highly selective electrochemical biosensor for the ultrasensitive detection of Hg2+ in aqueous solution has been developed based on the strong and specific binding of Hg2+ by two DNA thymine bases (T-Hg2+-T) and the use of AuNP-functionalized reporter DNA to achieve signal amplification.
