Oxidative stress induced by zero-valent iron nanoparticles and Fe(II) in human bronchial epithelial cells.
To identify the mechanism through which nanoparticulate zero-valent iron (nZVI; Fe0(s)) damages cells, a series of experiments were conducted in which nZVI in phosphate-buffered saline (PBS) was exposed to oxygen in the presence and absence of human bronchial epithelial cells. When nZVI is added to PBS, a burst of oxidants is produced as Fe0 and ferrous iron (Fe[II]) are converted to ferric iro...
متن کاملOxidative stress in microorganisms exposed to iron nanoparticles
Engineered iron nanoparticles, with sizes smaller than 100 nm, have been of high concern because of their promising capability in environmental remediation. Nanoparticles based on zero-valent iron (nZVI) have the potential not only to migrate in the environment and interact with pollutants but also influence the living organisms by direct impact or by changes of groundwater parameters. The basi...
متن کاملCharacterization of zero-valent iron nanoparticles.
The iron nanoparticle technology has received considerable attention for its potential applications in groundwater treatment and site remediation. Recent studies have demonstrated the efficacy of zero-valent iron nanoparticles for the transformation of halogenated organic contaminants and heavy metals. In this work, we present a systematic characterization of the iron nanoparticles prepared wit...
متن کاملDegradation of Lindane by Zero-Valent Iron Nanoparticles
Thus far, zero-valent iron has been studied mostly for the degradation of structurally simple oneand two-carbon halogenated organic contaminants such as chlorinated methanes, ethanes, and ethenes. In this research, laboratory synthesized particles of nanoscale iron were explored to degrade lindane, also known as -hexachlorocyclohexane, a formerly widely utilized pesticide and well-documented pe...
متن کاملAntimicrobial and Genotoxicity Effects of Zero-valent Iron Nanoparticles
BACKGROUND In a world of nanotechnology, the first concern is the potential environmental impact of nanoparticles. An efficient way to estimate nanotoxicity is to monitor the responses of bacteria exposed to these particles. OBJECTIVES The current study explored the antimicrobial properties of nZVI (zero-valent Iron nanoparticles) on the Gram-negative bacterial systems Erwinia amylovora, Xant...
