How about a test that identifies Salmonella in five minutes, so that shipments of lettuce can be confiscated before they reach the table? Scientists today described development and successful testing of just such a test in a presentation here at the 243rd National Meeting and Exposition of the American Chemical Society (ACS).
Amid concerns about possible terrorist attacks with nuclear materials, and fresh memories of environmental contamination from the 2011 Fukushima Daiichi nuclear disaster in Japan, scientists today described development of a capsule that can be dropped into water, milk, fruit juices and other foods to remove more than a dozen radioactive substances.
Using nanoparticles and alternating magnetic fields, University of Georgia scientists have found that head and neck cancerous tumor cells in mice can be killed in half an hour without harming healthy cells.
The unique electrical properties of graphene have enticed researchers to envision a future of fast integrated circuits made with the one-carbon-atom-thick sheets, but many challenges remain on the path to commercialization. Scientists from the University of Florida have recently tackled one of these challenges - how to reliably manufacture graphene on a large scale.
In light of the expected increase in the application of nanotechnologies to medical devices, the Scientific Committee on Emerging and Newly Identified Health Risks (SCENIHR) is requested to provide a risk assessment of medical devices containing nanomaterials.
Sandia National Laboratories is using its Ion Beam Laboratory (IBL) to study how to rapidly evaluate the tougher advanced materials needed to build the next generation of nuclear reactors and extend the lives of current reactors.
The IEEE Photonics Conference 2012 (IPC-2012), previously known as the IEEE LEOS Annual Meeting, announces a Call for Papers. The conference will be held 23 - 27 September, 2012 in the San Francisco Bay area.
Like the colorful temporary tattoos that children stick to their arms for fun, people may one day put thin "electronic skin" patches onto their arms to wirelessly diagnose health problems or deliver treatments.
Propelled by a transformative gift from a longtime contributor, the University of Miami is announcing the creation of the Dr. John T. Macdonald Foundation Biomedical Nanotechnology Institute, a collaboration of key scientific disciplines that will harness the field of nanotechnology for clinical applications.
A chemistry team at the University of Toronto has discovered environmentally-friendly iron-based nanoparticle catalysts that work as well as the expensive, toxic, metal-based catalysts that are currently in wide use by the drug, fragrance and food industry.
During the international workshop Nanobruecken II at INM - Leibniz Institute for New Materials on 22 and 23 March 2012, materials researchers from Europe discussed why mechanical properties of a material change in smallest dimensions.
