A new study from researchers at North Carolina State University sheds light on how a technique that is commonly used for making single-metal nanoparticles can be extended to create nanoparticles consisting of two metals "“ and that have tunable properties. The study also provides insight into the optical properties of some of these nanoparticles. Tuning the optical properties of nanoparticles is of interest for applications such as security technology, and for use in making chemical...

MU scientists make strides in green nanotechnology Gold nanoparticles, tiny pieces of gold so small that they can't be seen by the naked eye, are used in electronics, healthcare products and as pharmaceuticals to fight cancer. Despite their positive uses, the process to make the nanoparticles requires dangerous and extremely toxic chemicals. While the nanotechnology industry is expected to produce large quantities of nanoparticles in the near future, researchers have been worried about the...

New technique can sense movement of single molecules over hours Scientists can detect the movements of single molecules by using fluorescent tags or by pulling them in delicate force measurements, but only for a few minutes. A new technique by Rice University researchers will allow them to track single molecules without modifying them -- and it works over longer timescales. In the current issue of Nanotechnology, a team led by Jason Hafner, an associate professor of physics and astronomy and...
