Electrochemical Sensor for Mercury(II) Based on Conformational Switch Mediated by Interstrand Cooperative Coordination

A novel electrochemical sensor was developed for sensitive and selective detection of mercury(II), based on thymine−Hg2+−thymine (T−Hg2+−T) coordination chemistry. This strategy exploited the cooperativity of proximate poly-T oligonucleotides in coordination with Hg2+. Ferrocene (Fc)-tagged poly-T o...
