Scientists at the University of Southampton have identified key characteristics that enhance a nanoparticle's ability to penetrate skin, in a milestone study which could have major implications for the delivery of drugs. ...> Full Article


All that glitters is... slimy? Gold nanoparticles measure the stickiness of snot (10/21/2014)

Researchers at the University of North Carolina at Chapel Hill have developed a way to use gold nanoparticles and light to measure the stickiness of mucus in the airways. Their research, being presented at Frontiers in Optics, could help doctors better monitor and treat lung diseases such as cystic fibrosis and chronic obstructive pulmonary disease. ...> Full Article


Drug-infused nanoparticle is right for sore eyes (10/20/2014)

Drug-infused nanoparticle is right for sore eyesFor the millions of sufferers of dry eye syndrome, their only recourse to easing the painful condition is to use drug-laced eye drops three times a day. Now, researchers from the University of Waterloo have developed a topical solution containing nanoparticles that will combat dry eye syndrome with only one application a week. ...> Full Article


Smallest world record has 'endless possibilities' for bio-nanotechnology (10/19/2014)

Scientists from the University of Leeds have taken a crucial step forward in bio-nanotechnology, a field that uses biology to develop new tools for science, technology and medicine. ...> Full Article


Nanoparticles break the symmetry of light (10/18/2014)

Nanoparticles break the symmetry of lightIf a particle emits light into one direction, it usually emits just as much light into the opposite direction. By coupling gold particles to glass fibers, scientists from the Vienna University of Technology have succeeded in breaking this symmetry. This turns the gold particle into a switch which can direct light into two different directions in a glass fiber cable. ...> Full Article


Fast, cheap nanomanufacturing (10/17/2014)

Arrays of tiny conical tips that eject ionized materials could fabricate nanoscale devices cheaply. ...> Full Article


Nano-bearings on the test bench (10/16/2014)

Nano-bearings on the test bench'Nano-machines of the future will need tiny devices to reduce friction and make movement possible. The C60 molecule, also known as fullerene or buckyball, seemed to many an excellent candidate for nano-bearings. Unfortunately, the results so far have been conflicting, calling for further studies, like the one carried out by a theoretical team involving the International School for Advanced Studies, the International Center for Theoretical Physics, the National Research Council and the Swiss Federal Laboratories for Materials Science and Technology. Through a series of computer simulations the scientists uncovered the reason for the experimental discrepancies. ...> Full Article

All directions are not created equal for nanoscale heat sources (10/15/2014)

All directions are not created equal for nanoscale heat sourcesThermal considerations are rapidly becoming one of the most serious design constraints in microelectronics, especially on submicron scale lengths. A study by researchers from the University of Illinois at Urbana-Champaign has shown that standard thermal models will lead to the wrong answer in a three-dimensional heat-transfer problem if the dimensions of the heating element are on the order of one micron or smaller. ...> Full Article


Nanoparticles accumulate quickly in wetland sediment (10/14/2014)

Nanoparticles accumulate quickly in wetland sedimentUsing mesocosms that closely approximate wetland ecosystems, researchers show carbon nanotubes accumulate quickly in sediments -- a tendency that could indirectly damage aquatic food chains by piggybacking harmful molecules. ...> Full Article


A new dimension for integrated circuits: 3-D nanomagnetic logic (10/13/2014)

A new dimension for integrated circuits: 3-D nanomagnetic logicElectrical engineers at the Technische Universitat Munchen have demonstrated a new kind of building block for digital integrated circuits. Their experiments show that future computer chips could be based on three-dimensional arrangements of nanometer-scale magnets instead of transistors. As CMOS, the main enabling technology of the semiconductor industry, approaches fundamental limits, Technische Universitat Munchen researchers and collaborators at Notre Dame are exploring 'magnetic computing' as an alternative. They report their latest results in the journal Nanotechnology. ...> Full Article


Researchers develop new transparent nanoscintillators for radiation detection (10/12/2014)

Researchers develop new transparent nanoscintillators for radiation detectionUS Department of Homeland Security-funded researchers in Texas have identified radiation detection properties in a light-emitting nanostructure made in a new way from two of the least expensive rare earth elements. Their work is being published this week in Optics Letters. ...> Full Article
