Precocious GEM: Shape-shifting sensor can report conditions from deep in the body
(National Institute of Standards and Technology (NIST)) Scientists working at NIST and NIH have devised and demonstrated a new, shape-shifting probe, about one-hundredth as wide as a human hair, which is capable of sensitive, high-resolution remote biological sensing that is not possible with current technology. If eventually put into widespread use, the design could have a major impact on research in medicine, chemistry, biology and engineering. Ultimately, it might be used in clinical diagnostics.

Solving molybdenum disulfide's 'thin' problem
(Northwestern University) A Northwestern University research team used silver nanodiscs to increase the promising new material's light emission by twelve times, making it a better candidate for light-emitting diode technologies.

A first glimpse inside a macroscopic quantum state
(ICFO-The Institute of Photonic Sciences) Science News reports on detection of particle entanglement in a beam of squeezed light. ICFO researchers were able to observe effects of entanglement monogamy, where particles can be strongly entangled only if they have few entanglement partners.

Nanoscale worms provide new route to nano-necklace structures
(Georgia Institute of Technology) Researchers have developed a novel technique for crafting nanometer-scale necklaces based on tiny star-like structures threaded onto a polymeric backbone. The technique could provide a new way to produce hybrid organic-inorganic shish kebab structures from semiconducting, magnetic, ferroelectric and other materials that may afford useful nanoscale properties.

Chemists make new silicon-based nanomaterials
(Brown University) Chemists from Brown University have found a way to make new 2-D, graphene-like semiconducting nanomaterials using an old standby of the semiconductor world: silicon.

UT Dallas engineers twist nanofibers to create structures tougher than bulletproof vests
(University of Texas at Dallas) Researchers at UT Dallas have created materials that exploit the electromechanical properties of specific nanofibers to stretch to up to seven times their length, while remaining tougher than Kevlar.

Designer's toolkit for dynamic DNA nanomachines
(Technische Universitaet Muenchen) Researchers at the Technische Universitaet Muenchen have demonstrated a new approach to joining -- and reconfiguring -- modular DNA building units, by snapping together complementary shapes instead of zipping together strings of base pairs. This not only opens the way for practical nanomachines with moving parts, but also offers a toolkit that makes it easier to program their self-assembly. The team, led by 2015 Leibniz Prize awardee professor Hendrik Dietz, published their results in Science.

ORNL-led team demonstrates desalination with nanoporous graphene membrane
(DOE/Oak Ridge National Laboratory) Desalination is an energy-intensive process, which concerns those wanting to expand its application. Now, a team of experimentalists led by the Department of Energy's Oak Ridge National Laboratory has demonstrated an energy-efficient desalination technology that uses a porous membrane made of strong, slim graphene -- a carbon honeycomb one atom thick. The results are published in the March 23 advance online issue of Nature Nanotechnology.

Sensor cable monitors fences of all kinds and can even detect low-level drone fly-bys
(Saarland University) Fenced-in areas, such as airports, nuclear power stations, industrial sites, or private plots of land, can now be monitored thanks to novel sensor technology that has been developed by a team of experimental physicists, led by Professor Uwe Hartmann at Saarland University. The sensors respond immediately as soon as someone tries to climb over or cut through the fence, providing information on the precise location of the security breach.

Nanorobotic agents open the blood-brain barrier, offering hope for new brain treatments
(University of Montreal) Magnetic nanoparticles can open the blood-brain barrier and deliver molecules directly to the brain, say researchers from the University of Montreal, Polytechnique Montral, and CHU Sainte-Justine. This barrier runs inside almost all vessels in the brain and protects it from elements circulating in the blood that may be toxic to the brain. The research is important as currently 98 percent of therapeutic molecules are also unable to cross the blood-brain barrier.
