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.
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.
A Drexel University team of engineers, scientists and biologists have developed a carbon nanotube-based device for probing single living cells without damaging them. This technique will allow experts to identify diseases in their early stage and advance drug discovery.
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.
One of the rarest metals on Earth may be an excellent option for enabling future flash memory chips to continue increasing in speed and density, according to a group of researchers in Taiwan, who describe incorporating nanocrystals of iridium into critical components of flash memory.
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.
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.
SCF-III, in this series will provide a continued forum for discussions in this rapidly growing field of syntactic foams and composite foams. Syntactic foams and rigid polymer, metal, and ceramic foams containing a reinforcing and/or functional phase are the intended focus of this conference.
Although engineering has long played a key role in developing technology for diagnosing and treating human disease, it has only recently started to have an impact on understanding the cellular and molecular basis of disease. In the past decade or so, engineers have started making major contributions to understanding diseases such as malaria, hereditary blood diseases and cancer, according to Subra Suresh, former dean of MIT's School of Engineering.
