Abstract：

The　Au/(Peroxide　polypyrrole)/DNA　electrochemical　sensor　for　organic　pollutant　perfluorooctanoic　acid　was　prepared.　The　morphology　of　the　electrode　surface　was　characterized　by　atomic　force　microscopy　(AFM).　Electrochemical　response　of　the　sensor　to　perfluorooctanoic　acid　was　studied　by　using　methylene　blue　(MB)　as　the　indicator.　It　was　found　that　the　MB　peak　current　decreased　with　the　elongation　of　damage　time　and　the　increase　of　ionic　strength.　The　results　of　electrochemical　impedance　studies　showed　that　DNA　damage　reduced　the　electron　transfer　ability.
