Characterization of Metal Binding Peptides Derived from Copper Trafficking Proteins
(2010)Copper was first released into the environment as the result of the mass generation of oxygen from photosynthetic bacteria roughly 2.7 billion years ago. While it proved to be poisonous to early life on Earth, those that ... -
Deposition of silver nanoparticles in geochemically heterogeneous porous media: predicting affinity from surface composition analysis.
(2011)The transport of uncoated silver nanoparticles (AgNPs) in a porous medium composed of silica glass beads modified with a partial coverage of iron oxide (hematite) was studied and compared to that in a porous medium composed ... -
Emerging contaminant or an old toxin in disguise? Silver nanoparticle impacts on ecosystems.
(Environ Sci Technol, 2014-05-06)The use of antimicrobial silver nanoparticles (AgNPs) in consumer-products is rising. Much of these AgNPs are expected to enter the wastewater stream, with up to 10% of that eventually released as effluent into aquatic ecosystems ... -
Long-term transformation and fate of manufactured ag nanoparticles in a simulated large scale freshwater emergent wetland.
(Environ Sci Technol, 2012-07-03)Transformations and long-term fate of engineered nanomaterials must be measured in realistic complex natural systems to accurately assess the risks that they may pose. Here, we determine the long-term behavior of ... -
Low concentrations of silver nanoparticles in biosolids cause adverse ecosystem responses under realistic field scenario.
(PLoS One, 2013)A large fraction of engineered nanomaterials in consumer and commercial products will reach natural ecosystems. To date, research on the biological impacts of environmental nanomaterial exposures has largely focused ... -
Silver toxicity across salinity gradients: the role of dissolved silver chloride species (AgCl x ) in Atlantic killifish (Fundulus heteroclitus) and medaka (Oryzias latipes) early life-stage toxicity.
(Ecotoxicology, 2016-08)The influence of salinity on Ag toxicity was investigated in Atlantic killifish (Fundulus heteroclitus) early life-stages. Embryo mortality was significantly reduced as salinity increased and Ag(+) was converted to AgCl(solid). ... -
The effect of nanowire length and diameter on the properties of transparent, conducting nanowire films.
(Nanoscale, 2012-03-21)This article describes how the dimensions of nanowires affect the transmittance and sheet resistance of a random nanowire network. Silver nanowires with independently controlled lengths and diameters were synthesized with ...
