Abstract:
The fabrication of a novel nano Ag2O2-PbO2 modified electrode is described.Hydroxide radical could be generated on the surface of the electrode at an optimized potential.Lipid peroxidate and transudatory protein were detected to show destruction of cell membrane of E.coli treated by Ag2O2-PbO2 modified electrode.DNA damage of E.coli was studied in detail with electrophoresis and DNA sequence determination.The results show that cracking of plasmid DNA and mutation of gene sequence could be induced by nano Ag2O2-PbO2 modified electrode.
Key words: Nano Ag2O2-PbO2 modified electrode;E.coli;DNA damage, Nano AgO2-PbO2 modified electrode, E.coli, DNA damage
