The toxicity of antimicrobial silver in products can be reduced (2/27/2010)

Chemists at the University of Helsinki have managed to manufacture new polymer-stabilized silver nanoparticles. The result is significant because the antimicrobial characteristics of silver are used in textiles, floor coatings and paints even though the impact on health of silver nanoparticles are not entirely known. Finnish researchers now think that exposure to silver can be reduced by chemically binding the nanoparticles to polymers. The research results will soon be published in a leading journal in the field, Colloid and Polymer Science. ...> Full Article


Silver nanoparticles may one day be key to devices that keep hearts beating strong and steady (2/12/2010)

Diamonds and gold may make some hearts flutter on Valentine's Day, but in a University at Buffalo laboratory, silver nanoparticles are being designed to do just the opposite. ...> Full Article



An exquisite container (11/6/2009)

An exquisite containerA tiny cage of gold covered with a smart polymer responds to light, opening to empty its contents and resealing when the light is turned off. The smart nanocages could be used to deliver drugs directly to target sites, thus avoiding systemic side effects. ...> Full Article



Knocking nanoparticles off the socks (10/29/2009)

Knocking nanoparticles off the socksScientists in Switzerland are reporting results of one of the first studies on the release of silver nanoparticles from laundering those anti-odor, anti-bacterial socks now on the market. Their findings, scheduled for the Nov. 1 issue of ACS' journal Environmental Science & Technology, may suggest ways that manufacturers and consumers can minimize the release of these particles to the environment, where they could harm fish and other wildlife. ...> Full Article


Silver nanoparticles give polymer solar cells a boost (10/7/2009)

Small bits of metal may play a new role in solar power. Researchers at Ohio State University are experimenting with polymer semiconductors that absorb the sun's energy and generate electricity. The goal: lighter, cheaper and more-flexible solar cells. They have now discovered that adding tiny bits of silver to the plastic boosts the materials' electrical current generation. ...> Full Article

New silver nanoparticle skin gel for healing burns (7/23/2009)

New silver nanoparticle skin gel for healing burnsScientists in India are reporting successful laboratory tests of a new and potentially safer alternative to silver-based gels applied to the skin of burn patients to treat infections. The researchers describe gel composed of silver nanoparticles -- each 1/50,000th the width of a human hair -- that appears more effective than these traditional gels. Their study is scheduled for the Aug. 3 issue of ACS' Molecular Pharmaceutics, a bimonthly journal. ...> Full Article


New silver-based ink has applications in electronics, researchers say (2/17/2009)

A new ink, composed of silver nanoparticles, can be used in electronic and optoelectronic applications to create flexible, stretchable and spanning microelectrodes that carry signals from one circuit element to another. The printed microelectrodes can withstand repeated bending and stretching with minimal change in their electrical properties. ...> Full Article
