Lab on a ChipNIST focuses on testing standards to support lab on a chip commercialization Lab on a chip (LOC) devices are microchip-size systems that can prepare and analyze tiny fluid samples with volumes ranging from a few microliters (millionth of a liter) to sub-nanoliters (less than a billionth of a liter). A recent paper from the National Institute of Standards and Technology argues that before LOC technology can be fully commercialized, testing standards need to be developed and implemented.

Angwandte ChemieOh, my stars and hexagons! DNA code shapes gold nanoparticles DNA holds the genetic code for all sorts of biological molecules and traits. But University of Illinois researchers have found that DNA's code can similarly shape metallic structures. The team found that DNA segments can direct the shape of gold nanoparticles -- tiny gold crystals that have many applications in medicine, electronics and catalysis. Each of the four DNA bases codes for a different gold particle shape: rough round particles, stars, flat round discs, and hexagons.

Nature CommunicationsNew phenomenon in nanodisk magnetic vortices New findings from a team of Berkeley Lab and Japanese scientists suggest that the road to magnetic vortex RAM might be more difficult to navigate than previously supposed, but there might be unexpected rewards as well. A study at the Advanced Light Source revealed that contrary to suppositions, the formation of magnetic vortices in ferromagnetic nanodisks is an asymmetric phenomenon.

Nature PhysicsQuantum physics: New insights into the remote control of quantum systems An international collaboration led by physicists of the University of Vienna shines new light on the question of the resources required for achieving quantum information processing. The scientists demonstrate that less demanding resources, which are easier to prepare and to control, can be used for quantum-enhanced technologies. In the experiment, which is published in Nature Physics, the researchers achieve remote quantum state preparation without requiring entanglement as a resource. Contact: Philip Walther

NatureReluctant electrons enable 'extraordinarily strong' negative refraction Researchers at the Harvard School of Engineering and Applied Sciences have demonstrated a drastically new way of achieving negative refraction in a metamaterial. The advance, reported in the Aug. 2 issue of Nature, results in an "extraordinarily strong" negative refractive index as large as -700, more than a hundred times larger than most previously reported.

Nature NanotechnologyA giant step in a miniature world: UZH researcher measures the electrical charge of nano particles Nano particles are a millionth of a millimeter in size, making them invisible to the human eye. Unless, that is, they are under the microscope of Prof. Madhavi Krishnan, a biophysicist at the University of Zurich. Prof. Krishnan has developed a new method that measures not only the size of the particles but also their electrostatic charge. Up until now it has not been possible to determine the charge of the particles directly. Contact: Prof. Dr. Madhavi Krishnan
