利用电化学阻抗谱（EIS）研究了金属离子Mg2+、Zn2+、Ni2+和Co2+与肽核酸（PNAs）薄膜的相互作用，结果表明，除Mg2+与主链和核碱基的相互作用为主外，Zn2+、Ni2+和Co2+与PNA薄膜的相互作用均有利。
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.
