Killing bacteria by hacking plastics with silver and electricity

Researchers at the Swedish Medical Nanoscience Center at Karolinska Institutet have developed an innovative way of hacking conducting plastics so as to prevent bacterial growth using silver nanoparticles and a small electrical ...

Wiping out bacteria with nanoparticle-cotton fibers

Silver has been used as an antimicrobial agent for more than 100 years. Today, silver in the form of nanoparticles is incorporated in such products as plastic food containers, medical materials, and clothing. In textiles, ...

Can crab shells provide a 'green' solution to malaria?

A non-toxic mixture of chitin-rich crab shell powder and nanosized silver particles could be an environmentally friendly way of curbing the spread of disease-carrying mosquitoes, and malaria in particular. This is according ...

Silver circuits on foil allow curved touchscreens

Microscopically fine conductor paths are required on the surfaces of smartphone touchscreens. At the edges of the appliances, these microscopic circuit paths come together to form larger connective pads. Until now, these ...

A better understanding of nanomaterials

In the past six years, the National Research Programme "Opportunities and Risks of Nanomaterials" (NRP 64) intensively studied the development, use, behaviour and degradation of engineered nanomaterials, including their impact ...

Painting fingernails with silver and gold

Since ancient times, people have used lustrous silver, platinum and gold to make jewelry and other adornments. Researchers have now developed a new way to add the metals to nail polish with minimal additives, resulting in ...

Iron nanocubes may be key in the future of NO2 sensing

While nanoparticles sound like a recent discovery, these tiny structures have been used for centuries. The famous Lycurgus cup, made by 4th century Roman artisans, features dichroic glass, with gold and silver nanoparticles ...
