Herein, we report a simple and inexpensive way for the fabrication of a microelectrode, DNA modified carbon paste electrode (DNA-CPE). DNA is deposited onto carbon paste electrode surface by self-assembled monolayers. The electrochemical behaviour of DNA-CPE’s was studied by cyclic voltammetry (SWV) tests. The recorded CV’s showed two redox peacks simultaneously at E oxidation=0.3 V and E reduction=0.2 V. The recorded SWV curves at DNA-CPE have shown great efficiency in the analysis of mercury (II) at different concentrations.
