Nature Nanotechnology
Magnetic switching simplified
An international team of researchers has described a new physical effect that could be used to develop more efficient magnetic chips for information processing. The quantum mechanical effect makes it easier to produce spin-polarized currents necessary for the switching of magnetically stored information.

Self-healing solar cells 'channel' natural processes
To understand how solar cells heal themselves, look no further than the nearest tree leaf or the back of your hand. The "branching" vascular channels that circulate life-sustaining nutrients throughout leaves and hands serve as the inspiration for NC State University solar cells that can restore themselves efficiently and inexpensively.

Quantum communication controlled by resonance in 'artificial atoms'
Researchers at the Niels Bohr Institute, together with colleagues in the US and Australia, have developed a method to control a quantum bit for electronic quantum communication in a series of quantum dots, which behave like artificial atoms in the solid state. The results have been published in the scientific journal Physical Review Letters.

Making a mini Mona Lisa
Researchers at the Georgia Institute of Technology have "painted" the Mona Lisa on a substrate surface approximately 30 microns in width -- or one-third the width of a human hair. The team's creation, the "Mini Lisa," demonstrates a technique that could potentially be used to achieve nanomanufacturing of devices because the team was able to vary the surface concentration of molecules on such short-length scales.

Catching cancer early by chasing it
Reaching a clinic in time to receive an early diagnosis for cancer -- when the disease is most treatable -- is a global problem. And now a team of Chinese researchers proposes a global solution: have a user-friendly diagnostic device travel to the patient, anywhere in the world.

Using gold and light to study molecules in water
Thanks to a new device that is the size of a human hair, it is now possible to detect molecules in a liquid solution and observe their interactions. This is of major interest for the scientific community, as there is currently no reliable way of examining both the behavior and the chemical structure of molecules in a liquid in real time.Developed at Boston University, the process brings together infrared detection techniques and gold nanoparticles. The results have been published in Nature Communications.

Chemists develop innovative nano-sensors for multiple proteins
Chemists at Johannes Gutenberg University Mainz have developed a new method for parallel protein analysis that is, in principle, capable of identifying hundreds or even thousands of different proteins. It could be used to detect the presence of viruses and identify their type in tiny samples. At the same time, it is very cost-effective and quick.
