Voltammetric and chronopotentiometric measurements with nucleic acid-modified mercury film on a glassy carbon electrode
Mercury film plated on a glassy carbon electrode was used for the analysis of nucleic acids. Using voltammetry in cyclic, square-wave and alternating current modes and constant current chronopotentiometry redox as well as tensammetric signals of DNA, RNA and synthetic polynucleotides were obtained. Behavior of nucleic acids at the mercury film electrode (MFE) was compared with that observed previously at HMDE. Nucleic acid-modified MFE appeared suitable for various applications.
