Modeling Nanosilver Transformations in Freshwater Sediments
Environmental Science & Technology, 2013Silver nanoparticles (AgNPs), an effective antibacterial agent, are a significant and fast-growing application of nanotechnology in consumer goods. The toxicity of AgNPs released to surface waters during the use or disposal of AgNP-containing products will depend on the chemical transformations the nanoparticles undergo in the environment. We present a

Antibacterial Mechanism of Nanosilvers
Current Pharmacology Reports, 2019Due to antibiotic abuse, multiple drug-resistant bacteria have become the most threatening killers in the clinic. The alternative metal drugs, silver nanoparticles (AgNPs), thus exhibit huge antibacterial potential. Many studies have proved that the antibacterial efficacy of AgNPs depends on their concentration, size, surface charge, and coated ...

Polysaccharides templates for assembly of nanosilver
Carbohydrate Polymers, 2016Polysaccharides are particularly attractive in biomedical applications due to its biodegradability and biocompatibility. In addition to its ecofriendly effects and easy processing into different hydrogel shapes, made polysaccharides used on a large scale as suitable media for preparation of silver nanoparticles (AgNPs).

SOCKS AND OTHER GARMENTS that stay odor-free thanks to antimicrobial nanoscale silver particles are increasingly showing up on store shelves. But what happens to the silver when such products are washed remains an open question. New research by Bernd Nowack and colleagues at the Swiss Federal Laboratories for Materials Testing & Research provides a ...

Nanosilver: A nanoproduct in medical application
Toxicology Letters, 2008Nanotechnology is a most promising field for generating new applications in medicine. However, only few nanoproducts are currently in use for medical purposes. A most prominent nanoproduct is nanosilver. Nanosilver particles are generally smaller than 100nm and contain 20-15,000 silver atoms.

Predicting the environmental impact of nanosilver
Environmental Toxicology and Pharmacology, 2014Silver nanoparticles (AgNPs) are incorporated into many consumer and medical products due to their antimicrobial properties; however, the potential environmental risks of AgNPs are yet to be fully understood. This mini-review aims to predict the environmental impact of AgNPs, thus supplementing previous reviews on this topic.

A direct comparison of nanosilver particles and nanosilver plates for the oxidation of ascorbic acid
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2012We study of spherical silver nanoparticles of different size and Ag nanoplates were grown at zinc tin oxide (ZTO) surface and characterized using SEM. The application of different electrodes in voltammetry for determination ascorbic acid indicated that oxidation of this biomolecule occurs at these electrodes in diffusion controlled process.

Antibacterial activity by nanosilver particles
MRS Proceedings, 2012ABSTRACTThe antibacterial activity of nanosilver against Gram negative Escherichia coli bacteria is investigated by immobilizing nanosilver on nanostructured silica particles and closely controlling Ag content and size. These Ag/SiO2 nanoparticles were characterized by S/TEM, EDX spectroscopy, X-ray diffraction.

Curious germophobes can rejoice: Researchers have figured out how silver nanoparticles, found in many consumer products, kill bacteria. The culprits are the silver ions the nanoparticles emit, not nanoparticle-specific biological effects (Nano Lett., DOI: 10.1021/nl301934w). Manufacturers add silver nanoparticles to cosmetics and clothing to kill germs.
