Abstract
The interactions of the metal ions Mg2+, Zn2+, Ni2+, and Co2+ with thin films of peptide nucleic acids (PNAs) were studied by electrochemical impedance spectroscopy (EIS), and the results show that Zn2+, Ni2+ and Co2+ interacted favorably with the PNA film involving the backbone and the nucleobases with the exception of Mg2+ for which the interaction with the backbone appears to be dominant.
