Detecting lethal diseases with rust and sand

The next big thing in medical diagnostics could be minutes particles of rust, iron oxide, coated with the material from which sand is formed, silicon dioxide. These magnetic nanoparticles, a mere 29 to 230 nanometers across, ...

Virus killer gets supercharged

A simple technique to make a common virus-killing material significantly more effective is a breakthrough from the Rice University labs of Andrew Barron and Qilin Li.

Researchers discover new fluorescent silicon nanoparticles

Researchers in the Department of Physics and Astronomy at the University of Leicester have developed a new synthesis method, which has led them to the discovery of fluorescent silicon nanoparticles and may ultimately help ...

A silicon-nanoparticlephotonic waveguide

A new way to efficiently guide light at tiny scales has been demonstrated by an all-A*STAR team. Their method, which involves lining up silicon nanoparticles, is promising for applications such as light-based integrated circuits, ...
