A sensitive biosensor for mercury ions detection based on hairpin hindrance by thymine-Hg(II)-thymine structure

The exploitation of a dual-signal amplificatory electrochemical DNA biosensor was provided in this article, which can be used to detect Hg(II). One of the signal amplification units is nanocomposite modified electrode and the other is DNA-functionalized Au nanoparticle (DFNP), which include two type...
