 Biophysical JournalBacking out of the nanotunnel Nanopores provide a versatile tool for probing molecular structures. A new study shows that one can obtain more detailed information about the dynamic behavior of nucleic acids during passage through nanopores by directing them to asymmetric pores for the return journey.

PLOS ONEIn the brain, 'ORMOSIL' nanoparticles hold promise as a potential vehicle for drug delivery In the images of fruit flies, clusters of neurons are all lit up, forming a brightly glowing network of highways within the brain. It's exactly what University at Buffalo researcher Shermali Gunawardena was hoping to see: It meant that ORMOSIL, a novel class of nanoparticles, had successfully penetrated the insects' brains. And even after long-term exposure, the cells and the flies themselves remained unharmed. Contact: Charlotte Hsu

Reviews of Modern PhysicsSmaller and more powerful electronics requires the understanding of 'quantum jamming' physics Miguel A. Cazalilla, a scientist at the CFM and at the DIPC, both in San Sebastian, together with other four colleagues, was recently invited to write a review article for the prestigious journal Reviews of Modern Physics of the American Physical Society. The article, "One dimensional Bosons: From Condensed Matter to Ultracold Atoms," offers a glimpse into the recent progress in the field of one-dimensional quantum many-particle physics.

Nature MaterialsRelay race with single atoms: New ways of manipulating matter Thanks to a collaboration between scientists in San Sebastian and Japan, a relay reaction of hydrogen atoms at a single-molecule level has been observed in real-space. This way of manipulating matter could open up new ways to exchange information between novel molecular devices in future electronics. Dr. Thomas Frederiksen is one of the scientists that has participated in this research project. The results have been published in the prestigious journal Nature Materials. Contact: Aitziber Lasa

ScienceDown to the wire: Silicon links shrink to atomic scale The narrowest conducting wires in silicon ever produced are shown to have the same electrical current carrying capability as copper, as published in Science. This means electrical interconnects in silicon can be shrunk to the atomic-scale without losing their functionality – Ohm's law holds true at the atomic-scale. UNSW researchers will use these wires to address individual atoms – a key step in realizing a scalable quantum computer.

Physical Review Letters'Nanowiggles:' Scientists discover graphene nanomaterials with tunable functionality in electronics Scientists have used supercomputers to uncover the properties of a promising form of graphene, known as graphene nanowiggles. What they found was that graphitic nanoribbons can be segmented into several different surface structures called nanowiggles. Each of these structures produces highly different magnetic and conductive properties. The findings provide a blueprint that scientists can use to literally pick and choose a graphene nanostructure that is tuned and customized for a different task or device. Contact: Gabrielle DeMarco

ACS NanoThe art of molecular carpet-weaving Stable two-dimensional networks of organic molecules are important components in various nanotechnology processes. However, producing these networks, which are only one atom thick, in high quality and with the greatest possible stability currently still poses a great challenge. Scientists from the Excellence Cluster Nanosystems Initiative Munich have now successfully created just such networks made of boron acid molecules. The current issue of the scientific journal ACS Nano reports on their results.

ACS NanoPenn engineers develop more effective MRI contrast agent for cancer detection Many imaging technologies and their contrast agents -- chemicals used during scans to help detect tumors and other problems -- involve exposure to radiation or heavy metals, which present potential health risks to patients and limit the ways they can be applied. In an effort to mitigate these drawbacks, new research from University of Pennsylvania engineers shows a way to coat an iron-based contrast agent so that it only interacts with the acidic environment of tumors, making it safer, cheaper and more effective than existing alternatives.
