Nanotechnology News - November 2007 Archives
A wireless, nano-scale voltmeter developed at the University of Michigan is overturning conventional wisdom about the physical environment inside cells. It may someday help researchers tackle such tricky medical issues as why cancer cells grow out of control and how damaged nerves might be mended.

 | Scientists have devised remotely controlled nanoparticles that, when pulsed with an electromagnetic field, release drugs to attack tumors. The innovation, reported in the Nov. 15 online issue of Advanced Materials, could lead to the improved diagnosis and targeted treatment of cancer. ...> Full Article |
A team that includes two faculty affiliated with UD's Center for Composite Materials (CCM) and researchers from the Korea Institute of Materials (KIMS) has been selected to receive a $5 million grant from the Korea Ministry of Science and Technology (MOST) for work in the area of nanotechnology. Tsu-Wei Chou, Pierre S. du Pont Chair of Engineering, and Erik Thostenson, assistant professor of mechanical engineering, will lead the UD effort in the nine-year program.

 | A tiny sensor that can detect magnetic field changes as small as 70 femtoteslas-equivalent to the brain waves of a person daydreaming-has been demonstrated at the National Institute of Standards and Technology (NIST). The sensor could be battery-operated and could reduce the costs of non-invasive biomagnetic measurements such as fetal heart monitoring. The device also may have applications such as homeland security screening for explosives. ...> Full Article |
 | Bulletproof jackets do not turn security guards, police officers and armed forces into Robocops, repelling the force of bullets in their stride. New research in carbon nanotechnology however could give those in the line of fire materials which can bounce bullets without a trace of damage. ...> Full Article |
 | Make way for the real nanopod and make room in the Guinness World Records. A team of researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley have created the first fully functional radio from a single carbon nanotube, which makes it by several orders of magnitude the smallest radio ever made. ...> Full Article |
 | Nanotechnology could revolutionize the natural gas industry across the whole lifecycle from extraction to pollution reduction or be an enormous missed opportunity, claim two industry experts writing in Inderscience's International Journal of Nanotechnology. They suggest that nanotechnology could help us extract more fuel and feedstock hydrocarbons from dwindling resources. However, industry inertia and a lack of awareness of the benefits could mean a missed opportunity. ...> Full Article |
