A new DNA electrochemical biosensor is described for electrochemical impedance spectroscopy (EIS) detection of the sequence-specific DNA related to PAT transgene in the transgenic plants. Poly-2,6-pyridinedicarboxylic acid film (PDC) was fabricated by electropolymerizing 2,6-pyridinedicarboxylic acid on the glassy carbon electrode (GCE). The gold nanoparticles (NG) were modified on the PDC/GCE to prepare NG/PDC/GCE, and then DNA probe (ssDNA) was immobilized on the NG/PDC/GCE by the interaction… Expand
