HTTP:: New Class of Sensitive Nanosensors Created
--------
Scientists at the Oregon State University (OSU) have recently announced the creation of a new type of “plasmonic nanorod metamaterial,†which relies on the power of small, gold nanorods to create advanced nanosensors. The new devices could have a wide array of applications in fields ranging from medicine and biology to chemistry, ScienceDaily reports. According to the team, the new technology is at least ten times more sensitive than the next best thing, which could enable the creation of highly sensitive sensing devices, fit for detecting hazardous chemicals, or nuclear residues. “This is very exciting. It's an important new application of nanotechnology and the field of metamaterials, and should find some significant uses in medicine, chemistry and physics,†OSU Associate Professor of Physics Viktor Podolskiy, who has also been a member of the research team, explains. He adds that the new metamaterial is highly customizable, in that it can be made on a number of!
scales, according to specific needs. It can also be made to detect a wide array of substances and particles, which means that it could be used for bomb detection, or for detecting pathogens in polluted water. Metamaterials are a special class of structures that has weird properties, based not on its chemical makeup, but r...

Gold nanorods have been commercially available from Nanopartz for over two years. These nanorods are not a weird metamaterials - are made of gold, and can be used for all of the above applications and more. Nanopartz is producers of gold nanorods, spherical gold nanoparticles, gold nanowires,and more. Please visit them at www.nanopartz.com.
