Scientists have devised a way to explore how phase transitions -- changes of matter from one state to another without altering chemical makeup -- function in less than three dimensions and at the level of just a few atoms. ...> Full Article
The Micro and Nano Sensors Interest Group of the Sensors & Instrumentation KTN is organizing a conference and exhibition titled "Applications of Micro and Nanosensors in Security, Health and Environmental Monitoring" which will be held on the March 4, 2010, at National Physical Laboratory, Teddington, UK. This one-day event will showcase novel sensing technologies developed by UK companies and Universities leading to new applications in security, health and environmental monitoring. ...> Full Article
A collaborative research project has brought the world a step closer to producing a new material on which future nanotechnology could be based. Researchers across Europe, including the UK's National Physical Laboratory (NPL), have demonstrated how an incredible material, graphene, could hold the key to the future of high-speed electronics, such as micro-chips and touchscreen technology. ...> Full Article
Researchers at MIT and Harvard Medical School have built targeted nanoparticles that can cling to artery walls and slowly release medicine, an advance that potentially provides an alternative to drug-releasing stents in some patients with cardiovascular disease. ...> Full Article

Boron nitride nanotubes have been notoriously difficult to grow, requiring special instrumentation, dangerous chemistry, or temperatures of over 1,500 degrees Celsius to assemble. As it turns out, they just needed a little encouragement. Now, Michigan Tech physicist Yoke Khin Yap has created virtual Persian carpets of the tiny fibers on substrates made from simple catalysts. ...> Full Article

A Northwestern University study shows that coupling a magnetic resonance imaging contrast agent to a nanodiamond results in dramatically enhanced signal intensity and thus vivid image contrast. The researchers say it is a game-changing event for sensitivity and the first published report of nanodiamonds being imaged by MRI technology. The gadolinium(III)-nanodiamond complex demonstrated a greater than 10-fold increase in relaxivity -- among the highest per Gd(III) values reported to date. ...> Full Article
A strip of paper infused with carbon nanotubes can quickly and inexpensively detect a toxin produced by algae in drinking water. ...> Full Article
Aneeve Nanotechnologies LLC has licensed related carbon nanotube technology from UCLA that was developed by Kang Wang, professor of electrical engineering at UCLA. The CNT technology increases hormonal detection sensitivity significantly allowing detection beyond traditional sensors. The company is using this technology to develop bio-medical applications that are low power consumption, small in size, and involve ultra-sensitive nanoelectronic technologies. ...> Full Article

Scientists in Texas are reporting the development of a "nanodragster" that may speed the course toward development of a new generation of futuristic molecular machines. The vehicle -- only 1/50,000th the width of a human hair -- resembles a hot-rod in shape and can outperform previous nano-sized vehicles. Their report is in ACS' Organic Letters, a bi-weekly journal. ...> Full Article
