Research sheds light on how silver ions kill bacteria

The antimicrobial properties of silver have been known for centuries. While it is still a mystery as to exactly how silver kills bacteria, University of Arkansas researchers have taken a step toward better understanding the ...

Do kitchen items shed antimicrobial nanoparticles after use?

Because of their antimicrobial and antifungal properties, silver nanoparticles measuring between one and 100 nanometers (billionth of a meter) in size, are being incorporated outside the United States into a variety of kitchen ...

No chance for bacteria on implants

Hip and dental implant operations are routine. But not entirely risk-free. They may result in infection that is difficult to control with oral or intravenous antibiotics. In such cases, the implant will probably need to be ...

Individual silver nanoparticles observed in real time

Chemists at Ruhr-Universit├Ąt Bochum have developed a new method of observing the chemical reactions of individual silver nanoparticles, which only measure a thousandth of the thickness of a human hair, in real time. The ...

Real-time imaging of chemical processes

National University of Singapore scientists observe the real-time formation of hollow structures in the galvanic replacement (GR) reaction between silver and gold with nanometre resolution, gaining insights on the mechanisms ...
