title: Folding-based photoelectrochemical biosensor: binding-induced conformation change of a quantum dot-tagged DNA probe for mercury(II) detection.
abstract: Using CdS QD-tagged mercury-specific oligonucleotides, a novel folding-based photoelectrochemical sensor has been successfully fabricated for reagentless and highly sensitive Hg(2+) detection.
