Technology Update
Physicists in the UK have discovered another useful property of graphene – the material can be magnetized by simply passing a current of electrons through it. The effect could prove useful in creating spintronic or quantum-information devices that use the spin of the electron.
Electromagnetically induced transparency (EIT) is an optical process in atomic physics that occurs in certain media that do not usually transmit light at a certain wavelength.
Researchers in Australia and the US have developed a new way to print nanoparticle arrays.
New experiments by researchers at the University of Washington, Seattle, have looked at the roles of dopants in the photoluminescence of electrically active quantum dot films for the first time and have revealed remarkably large effects never previously observed.
Silver ions and nanosilver-containing coatings are well known for their biocide effects.
Nanotechnology offers a promising path to high-efficiency and low-cost next-generation solar cells.
More and more, nanopores are being used as stochastic sensors for biological molecules. Solid-state nanopores are good candidates for such a device and are often fabricated in an insulating membrane.
The Nanodermatology Society, a physician-led non-profit organization charged with monitoring nanotechnology as it relates to the diagnosis, prevention, and treatment of skin disease and evaluating their potential benefits or pitfalls, has released its first position statement on the safety of nanotechnology in sunscreens.
The Foods Standard Agency (FSA), a United-Kingdom based body independent of industry and government, has published a report of consumers’ views on the use of nanotechnology in food and food packaging.
A new discovery by a team of researchers from the United States and Switzerland could mean that scratches on your new car could repair themselves.
A leading nanotechnology scientist, Mike Kelly, a professor at the Center for Advanced Photonics and Electronics at the University of Cambridge, United Kingdom, has claimed, in a paper published in the journal Nanotechnology, that there is a limit to how small nanotechnology materials can be mass produced.
Nanotechnology is often touted as a solution to many of the global ills facing our planet. It is expected to have a significant impact on developing “green” and “clean” technologies, improving water treatment, and making renewable energy applications profitable.
The process of drug development could be significantly speeded up due to a new biosensor microchip that holds more than 100,000 magnetically sensitive nanosensors.
Researchers at the University of Technology, Sydney, in Australia, have developed a composite material based on graphite that is as thin as paper and ten times stronger than steel.
In this blog, Andrew Maynard, Director of the Risk Science Center at the University of Michigan, United States, discusses changes in federal tone with regard to regulation of emerging technologies. In 2007, the White House Office of Science and Technology (OSTP) issued a set of “Principles for Nanotechnology Environmental, Health and Safety Oversight”, which had, […]
A new transistor that is comprised of a single electron – an island only 1.5 nanometers in diameter – and operates with the addition of only one or two electrons, has been created by researchers at the University of Pittsburgh, in the United States.
Researchers at Sandia National Laboratories, the University of New Mexico (UNM), and the UNM Cancer Research and Treatment Center, all in the United States, have produced a protocell that uses nanoparticles to blast cancerous cells with a mélange of killer drugs.
Scientists at the University of Michigan, United States, have made, for the first time, biodegradable polymers that can self-assemble into hollow, nanofiber spheres, which can, when injected with cells into wounds, biodegrade, but the cells live on to form new tissue.
The main risk for human health arising from engineered nanomaterials may be chronic occupational inhalation exposure, especially during activities of high particle release and uncontrolled exposure, according to basic risk assessments performed by scientists from the Institute for Health and Consumer Protection (IHCP)
Andrew Maynard, Director of the Risk Science Center at the University of Michigan, United States, says the discussions over regulation of nanomaterials are concerning as the seem to be driven less by the science of how these materials might cause harm, and more by the politics of confusion and uncertainty.
Norwegian researchers assessed the uptake, excretion and biodistribution of nanoparticles in the earthworm Eisenia fetida.
