Silver nanoparticles trap mercury

(PhysOrg.com) -- Anyone who thinks amalgams are limited to tooth fillings is missing something: Amalgams, which are alloys of mercury and other metals, have been used for over 2500 years in the production of jewelry and for ...

Investigating the environmental impact of nanosilver

When it comes to materials used in the fight against bacteria, silver may not be the first substance which comes to mind. However, the precious metal has been used in the medical industry as a biocide - a substance which ...

E-whiskers: Researchers develop highly sensitive tactile sensors

(Phys.org) —From the world of nanotechnology we've gotten electronic skin, or e-skin, and electronic eye implants or e-eyes. Now we're on the verge of electronic whiskers. Researchers with Berkeley Lab and the University ...

Rampant use of antibacterial nanosilver is a resistance risk

Researchers at the University of Technology Sydney warn that the broad-spectrum antimicrobial effectiveness of silver is being put at risk by the widespread and inappropriate expansion of nanosilver use in medical and consumer ...

Some antibacterials come with worrisome silver lining

Silver has long been known for its ability to kill some of the nasty microbes that can make people sick. In hospitals, it's used to help burn victims, to combat germs on catheters and even to wipe out dangerous "superbugs" ...
