Abstract
With exonuclease III activity on DNA hybrids containing thymine-Hg(2+)-thymine, a label-free ultrasensitive "turn-on" fluorescent sensor involving "quenching" and "reappearing" processes based on a carbon nanotube-Ag nanoclusters system is demonstrated for amplified determination of Hg(2+).
