Researchers have developed a convenient mass-synthesis method for nanotubes which uses less than one thousandth of the solvent used in conventional methods, and the time required for the drying process is only a few hours.
The tiny fibers that comprise blood clots show extraordinary elasticity, on average stretching to almost three times their length while still retaining their ability to go back to their normal shape and expanding to more than four times their length before breaking.
When smooth surfaces that hate water approach each other underwater, scientists have observed that they snap into contact. This is apparently due to attractive forces that extend for tens to hundreds of nanometers.
Scientists at the University of North Carolina at Chapel Hill have developed a new method to create computed tomography (CT) images using carbon nanotube x-rays that works much faster than traditional scanners and uses less peak power.
In a continuing effort to find out if the tiniest airborne particles pose a health risk, University of Rochester Medical Center scientists showed that when rats breathe in nano-sized materials they follow a rapid and efficient pathway from the nasal cavity to several regions of the brain.
Georgia Tech researchers have found a way to shrink all the sensing power of sophisticated biosensors, such as sensors that can detect trace amounts of a chemical in a water supply or a substance in your blood, onto a single microchip.
Engineers at Purdue University have developed a technique to grow individual carbon nanotubes vertically on top of a silicon wafer, a step toward making advanced electronics, wireless devices and sensors using nanotubes by stacking circuits and components in layers.
By combining peptide-based polymers with modified iron oxide nanoparticles, researchers have developed nanoparticles that can be manipulated in a magnetic field and that can respond to changes in pH and other physiologic stimuli.
