There are plenty of effective anticancer agents around. The problem is that, very often, they cannot gain access to all the cells in solid tumors. A new gene delivery vehicle may provide a way of making tracks to the heart of the target.
Partners from all over Europe will investigate the European labour market for personnel trained in nanotechnology. The relevance of existing nanotechnology education and training in universities, vocational training institutes and secondary schools for the needs of industrial and other employers will also be explored. By 2015, a model curriculum will be made available online.
Using DESY's X-ray laser FLASH, a team of scientists from Hamburg has traced the ultrafast explosion of iodine molecules. The group used the X-ray laser as a kind of high-speed camera - the observed molecular explosion took place within a millionth of a billionth of a second (i.e. within femtoseconds).
Researchers found that the offspring of water fleas (Daphnia magna) exposed to nanoparticles of titanium dioxide react significantly more sensitively than the offspring of parents from a control group. This is the case even though the offspring themselves are not exposed to the nanoparticles.
Researchers at MIT have fabricated a three-dimensional, lightweight metamaterial lens that focuses radio waves with extreme precision. The concave lens exhibits a property called negative refraction, bending electromagnetic waves - in this case, radio waves - in exactly the opposite sense from which a normal concave lens would work.
Drawing heavily upon nature for inspiration, a team of researchers has created a new artificial lens that is nearly identical to the natural lens of the human eye. This innovative lens, which is made up of thousands of nanoscale polymer layers, may one day provide a more natural performance in implantable lenses to replace damaged or diseased human eye lenses, as well as consumer vision products; it also may lead to superior ground and aerial surveillance technology.
We can look through glass, but what glass itself looks like on the inside has so far remained a mystery - at least as far as the precise position of the atoms is concerned. Scientists at the Fritz-Haber-Institute of the Max Planck Society in Berlin are now the first to have imaged the network of silicon and oxygen atoms - the main components of glass - in a silica film.
Researchers have presented an extensive analysis of the role of nanomaterialsin environmental remediation and monitoring. Nanomaterials can be used to clean up toxins and bacteria from natural waters, wastewaters and the air.
Röntgenstrahlen in einer Box 'auf Eis zu legen' und später nach Belieben wieder freizusetzen, klingt nach Science Fiction. Neue Rechnungen zeigen jedoch, dass mithilfe eines Magnetfelds einzelne Röntgenquanten eingefangen und ohne Qualitätsverlust wiedergewonnen werden können. Ausserdem ist es möglich, das gespeicherte Röntgenquant zu manipulieren, insbesondere seine Phase kontrolliert zu ändern.
Researchers at the Department of Energy's Oak Ridge National Laboratory have reported progress in fabricating advanced materials at the nanoscale. The spontaneous self-assembly of nanostructures composed of multiple elements paves the way toward materials that could improve a range of energy efficient technologies and data storage devices.
A University of Texas at Arlington physics professor has helped create a hybrid nanomaterial that can be used to convert light and thermal energy into electrical current, surpassing earlier methods that used either light or thermal energy, but not both.
Scientists in Spain have succeeded in eliminating infectious bacteria from medical textiles by using an enzymatic pre-treatment combined with simultaneous deposition of nanoparticles and biopolymers under ultrasonic irradiation.
