The interactions of the metal ions Mg(2+), Zn(2+), Ni(2+), and Co(2+) with thin films of peptide nucleic acids (PNAs) were studied by electrochemical impedance spectroscopy (EIS), and the results show that Zn(2+), Ni(2+) and Co(2+) interacted favorably with the PNA film involving the backbone and the nucleobases with the exception of Mg(2+) for which the interaction with the backbone appears to be dominant.
通过电化学阻抗谱（EIS）研究了金属离子 Mg(2+)、Zn(2+)、Ni(2+) 和 Co(2+) 与肽核酸（PNA）薄膜的相互作用，结果表明 Zn(2+)、Ni(2+) 和 Co(2+) 与 PNA 薄膜相互作用良好，涉及到骨架和碱基，而 Mg(2+) 与骨架的相互作用似乎占主导地位。
