A simple, practical and reusable electrochemical aptasensor, based on thymine-Hg2+-thymine (T-Hg2+-T) coordination chemistry and nanoporous gold (NPG) for signal amplification, was designed for sensitive and selective detection of mercury ions (Hg2+). The thiol modified T-rich hairpin capture probe was self-assembled onto the surface of the NPG modified electrode for hybridizing with ferrocene-labeled T-rich probe in the presence of Hg2+ via T-Hg2+-T coordination chemistry. As a result, the hairpin capture probe was opened, and the ferrocene ta...
