Peptide nucleic acid as a selective recognition element for electrochemical determination of Hg2+

Peptide nucleic acid as a selective recognition element for electrochemical determination of Hg2+

A Bala, Ł Górski - Bioelectrochemistry, 2018 - Elsevier
A novel electrochemical PNA-based biosensor for the determination of Hg 2+ is described.
The receptor layer, containing single strands of polythymine PNA (peptide nucleic acid), was
formed at the surface of gold electrode. Due to the presence of thymine bases and peptide  …
