We report a highly sensitive electrochemical sensor for the detection of Hg2+ ions in aqueous solution by using a thymine (T)-rich, mercury-specific oligonucleotide (MSO) probe and gold nanoparticles ...

The obtained electrochemical sensor exhibited not only high sensitivity for the detection of chlorogenic acid with a detection limit of 7.8 nM and a wide linear range of 0.5 μM to 4 mM but also an ...
