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 ...

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 ...

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 ...

Nanowire 'inks' enable paper-based printable electronics

By suspending tiny metal nanoparticles in liquids, Duke University scientists are brewing up conductive ink-jet printer "inks" to print inexpensive, customizable circuit patterns on just about any surface.

Researchers create a tiny laser using nanoparticles

Researchers at Aalto University, Finland, are the first to develop a plasmonic nanolaser that operates at visible light frequencies and uses so-called dark lattice modes.

Scientists make silver nanowires based on DNA molecules

A team of researchers from Russia and Israel, including scientists from MIPT, has made nanowires from DNA molecules and silver nanoparticles. The research findings were published in Advanced Materials and are featured on ...
