UK nanodevice builds electricity from tiny pieces
A team of scientists at the National Physical Laboratory (NPL) and University of Cambridge has made a significant advance in using nano-devices to create accurate electrical currents. Electrical current is composed of billions and billions of tiny particles called electrons. NPL scientists have developed an electron pump – a nano-device –, which picks these electrons up one at a time and moves them across a barrier, creating a very well-defined electrical current.

Smart materials get SMARTer
Living organisms have developed sophisticated ways to maintain stability in a changing environment, withstanding fluctuations in temperature, pH, pressure, and the presence or absence of crucial molecules. The integration of similar features in artificial materials, however, has remained a challenge -- until now.

White LEDs directly on paper
Imagine a white luminous curtain waving in the breeze. Or wallpaper that lights up your room with perfect white light. The applications are not very far away. White LEDs, made from zinc oxide and a conducting polymer, can be manufactured directly on paper, as shown by Gul Amin in his doctoral thesis at Linköping University, Sweden.

Metamolecules that switch handedness at light-speed
A multi-institutional team of researchers that included Berkeley Lab scientists has created the first artificial molecules whose chirality can be rapidly switched from a right-handed to a left-handed orientation with a beam of light. This holds potentially huge possibilities for the application of terahertz technologies across a wide range of fields, including biomedical research, homeland security and ultrahigh-speed communications.

Tiny bubbles snap carbon nanotubes like twigs
A computer model from Rice University shows that long nanotubes bend and snap like a twig when blasted with ultrasonic energy. The research in the Proceedings of the National Academy of Sciences finds that short and long nanotubes behave differently during sonication. The discovery answers a longstanding question about the origin of competing power laws that were found in experiments on cutting nanotubes by sonication.

World's fastest camera, created by UCLA engineers, used to detect rogue cancer cells
Researchers at UCLA Engineering report integration of the world's fastest camera with advanced microfluidics and real-time image processing to classify cells in blood samples. The new blood screening technology boasts a throughput of 100,000 cells per second which is approximately 100 times higher than conventional imaging-based blood analyzers. The technology performs real-time detection of extremely rare cells in a large sample of normal cells with high sensitivity and statistical accuracy in a short period of time.

Novel nanotherapeutic delivers clot-busting drugs directly to obstructed blood vessels
Researchers at the Wyss Institute for Biologically Inspired Engineering at Harvard University have developed a novel biomimetic strategy that delivers life-saving nanotherapeutics directly to obstructed blood vessels, dissolving blood clots before they cause serious damage or even death. This new approach enables thrombus dissolution while using only a fraction of the drug dose normally required, thereby minimizing bleeding side effects that currently limit widespread use of clot-busting drugs.

Solar power from plastic foils
KIT intensifies printable organic solar cell research. A group of researchers headed by Dr. Alexander Colsmann at the Light Technology Institute will start work this month. The project is scheduled for a duration of four years and aims at enhancing the efficiency of organic solar cells to more than 10 percent. For this purpose, the researchers use tandem architectures combining solar cells of complementary absorption spectra. The Federal Ministry of Education and Research has granted funding of €4.25 million.

Breaking the skin barrier
"Getting under your skin" takes on new meaning thanks to Northwestern University research that could transform gene therapy. A team from the fields of dermatology and nanotechnology is the first to demonstrate the use of commercial moisturizers to deliver gene therapy with great potential for life-saving therapies for skin cancers. The drug -- consisting of novel spherical arrangements of nucleic acids -- penetrates the skin's layers and can selectively target disease-causing genes while sparing normal genes.
