By linking a pair of tiny "puddles" of a few dozen electrons sandwiched inside a semiconductor, researchers have enabled these two so-called "quantum dots" to become parts of a transistor - the vital switching component in computer chips. Future computers that use quantum dots to store and process digital information might outperform conventional computer circuits because of both the new transistors' smaller size and their potential to solve problems that would take centuries on today's machines.

"This is a very promising candidate for quantum computation," said Albert M. Chang, who is an adjunct professor of physics in Purdue's School of Science. "We believe this research will allow large numbers of quantum-dot switches to work together as a group, which will be necessary if they are ever to function as a computer's brain, or memory....read the wave

'Revitalize Manufacturing and Invest in the
Jobs of the Future,' Says John Kerry

OAK RIDGE, Tenn., — Researchers at the Department of Energy's Oak Ridge National Laboratory have developed a nanoscale technology for investigating biomolecular processes in single living cells. The new technology enables researchers to monitor and study cellular signaling networks, including the first observation of programmed cell death in a single live cell.

The "nanobiosensor" allows scientists to physically probe inside a living cell without destroying it. As scientists adopt a systems approach to studying biomolecular processes, the nanobiosensor provides a valuable tool for intracellular studies that have applications ranging from medicine to national security to energy production.

ORNL Corporate Fellow and Life Sciences Division researcher Tuan Vo-Dinh leads a team of researchers who are developing the nanoscale technology. "This research illustrates the integrated ‘nano-bio-info' approach to investigating and understanding these complex cell systems," Vo-Dinh said. "There is a need to explore uncharted territory inside a live cell and analyze the molecular processes. This minimally invasive nanotechnology opens the door to explore the inner world of single cells". ...read the wave

To Capsulution this represents an important patent from a range of patent families, which the company had in-licensed exclusively for worldwide marketing from Garching Innovation GmbH - the technology transfer office of the Max Planck Society. In addition to these, Capsulution in recent years filed further patent applications regarding newly developed applications of the LBL-Technology®. By means of this technology capsules are manufactured by the layerwise adsorption of polyelectrolytes onto the encapsulated compounds.

Dr. Andreas Voigt, CSO of Capsulution said: "The recently granted patent further sharpens our competitive edge as a developer of innovative nano- and micro-capsules for high-end applications in the fields of drug-delivery. We are also confident to identify further fields of application where the use of novel capsules with non-spherical shapes will lead to substantially increased benefits." In line with Capsulution's corporate strategy several further developments of this technology are to be protected by patent applications in coming years.

Diagnostic method based on nanoscience could rival PCR

EVANSTON, Ill. --- Since the advent of the polymerase chain reaction (PCR) nearly 20 years ago, scientists have been trying to overturn this method for analyzing DNA with something better. The "holy grail" in this quest is a simple method that could be used for point-of-care medical diagnostics, such as in the doctor's office or on the battlefield.

Now chemists at Northwestern University have set a DNA detection sensitivity record for a diagnostic method that is not based on PCR -- giving PCR a legitimate rival for the first time. Their results were published online today (April 27) by the Journal of the American Chemical Society (JACS).

"We are the first to demonstrate technology that can compete with -- and beat -- PCR in many of the relevant categories," said Chad A. Mirkin, director of Northwestern's Institute for Nanotechnology, who led the research team. "Nanoscience has made this possible. Our alternative method promises to bring diagnostics to places PCR is unlikely to go -- the battlefield, the post office, a Third World village, the hospital and, perhaps ultimately, the home." ...read the wave

IBM, Stanford Collaborate on World-Class Spintronics Research

SAN JOSE, Calif.--(BUSINESS WIRE) --IBM and Stanford University are joining forces on the advanced research and creation of new high-performance, low-power electronics in the emerging field of nanotechnology called "spintronics." To formalize the effort, scientists at IBM's Almaden Research Center and Stanford University today announced the formation of the IBM-Stanford Spintronic Science and Applications Center (SpinAps, for short).

"SpinAps researchers will work to create breakthroughs that could revolutionize the electronics industry, just as the transistor did 50 years ago," said Dr. Robert Morris, IBM VP and director of the Almaden Research Center.

Since its inception, the microelectronics industry has progressed by shrinking circuitry. This approach is becoming much more difficult, time-consuming and expensive, and there is now a worldwide search for new ideas that can deliver improved performance in smaller sizes than is possible with conventional designs. Spintronics is an exciting possibility because controlling the spin -- or magnetic orientation -- of electrons within tiny structures made of ultra-thin layers can produce such advantageous properties as low-power switching and nonvolatile information storage....read the wave
