제목 The Antibacterial Mechanism of Zero-Valent Iron Nanoparticles : Generation of Intracellular Oxidants and Damage on the Cell Membrane
초록 Nano particulate zero-valent iron (nZVI) and ferrous ion (Fe[II]) exhibited strong bactericidal effects on E. coli under deaerated conditions. The E. coli inactivation efficiency successfully correlated with the production of intracellular oxidants, which suggests that the oxidants are produced by the reactions of nZVI and Fe(II) with the oxygen present inside or on the surface of the cells under deaerated conditions. Significant disturbances of the cell membrane and respiratory activity were observed in the E. coli cells treated by nZVI and Fe(II) under deaerated conditions.
