 | 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.

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.

 | Nanoscience has the potential to play an enormous role in enhancing a range of products, including sensors, photovoltaics and consumer electronics. Scientists in this field have created a multitude of nano scale materials, such as metal nanocrystals, carbon nanotubes and semiconducting nanowires. ...> 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 |
Researchers have created biodegradable nanosized particles that can easily slip through the body's sticky and viscous mucus secretions to deliver a sustained-release medication cargo.
