Label-Free Electrochemical Biosensor of Mercury Ions Based on DNA Strand Displacement by Thymine-Hg(II)-Thymine Complex

A novel electrochemical biosensor for the determination of mercury ions in aqueous solution has been reported. The sensing substrate with a layer of gold nanoparticles on the gold electrode surface was formed through 1,6‐hexanedithiol connection, which could enhance the surface loading of the captur...
