Nanoscale gene 'ignition switch' may help spot and treat cancer

In a proof of principal study in mice, scientists at Johns Hopkins and the Virginia Commonwealth University (VCU) have shown that a set of genetic instructions encased in a nanoparticle can be used as an 'ignition switch' to rev up gene activity that aids cancer detection and treatment.

Hot embossing glass - to the nearest micrometer

The lens is what matters: if lens arrays could be made of glass, it would be possible to make more conveniently sized projectors. Fraunhofer researchers have now developed a process that allows this key component to be mass produced with extreme accuracy.

Online Workshop: Nanotechnology for Solar Energy

Despite its current elusiveness in many parts of the northern hemisphere, no-one can boycott the sun! Harnessing nanotechnology development for sustainable energy enables us to focus on energy security and move away from our dependence on an ever-depleting supply of fossil fuels from regions that are often destabilised through ownership of these resources.

Making wafers faster by making features smaller

Manufacturing semiconductors for electronics involves etching small features onto wafers using lasers, a process that is limited by the wavelength of the light itself. The development of a new, intense 13.5-nm light source will resolve this issue by reducing the feature size by an order of magnitude or so.

Single quantum dot nanowire photodetectors

Moving a step closer toward quantum computing, a research team in the Netherlands recently fabricated a photodetector based on a single nanowire, in which the active element is a single quantum dot with a volume of a mere 7,000 cubic nanometers.
