Clarification: Carbon nanotubes study performed on mice

Weekly reported on a new study that shows some potential for carbon nanotubes to behave like asbestos if inhaled. We failed to report, however, that the study was conducted by injecting carbon nanotubes into the abdomen of mice. Conclusions reached about the inhalation risk of carbon nanotubes were made by researchers involved in the project based on results of the injection regime. There is, as yet, no direct evidence that inhalation of carbon nanotubes poses a health risk, and researchers involved in the study acknowledged that more experimentation is required to fully assess inhalation risk.

Nanotubes "As Deadly as Asbestos"

Stony Stevenson writes "Certain carbon nanotubes may be as hazardous to humans as asbestos. A paper to be published in Nature Nanotechnology suggests that inhaling certain types of nanotubes can lead to the formation of mesothelioma, a type of lung cancer commonly caused by exposure to asbestos. "This is a wakeup call for nanotechnology in general and carbon nanotubes in particular," said Andrew Maynard, co-author of the report and chief science adviser to the Project on Emerging Nanotechnologies." I'm really hoping that those medical face masks get popular again. That's a look that should really be cyclic, like bell-bottoms and thongs. Update: 05/21 19:18 GMT by T : See also this page at the Nanotechnology Project, which features a link to video commentary from Andrew Maynard, the researcher mentioned in the above-linked article.

Some Nanotubes Could Cause Cancer

Certain types of carbon nanotubes could cause the same health problems as asbestos, according to the results of two recent studies. In one, published yesterday, tests in mice showed that long and straight multiwalled carbon nanotubes cause the same kind of inflammation and lesions in the type of tissues that surround the lungs that is caused by asbestos. The other study, also done in mice, showed that similar carbon nanotubes eventually led to cancerous tumors.

Spin Control: New Technique Sorts Nanotubes by Length

In a schematic of NIST's length separation technique for carbon nanotubes (l.), the nanotubes start at the bottom of a dense fluid. When spun in a centrifuge, the nanotubes begin to migrate through the fluid driven by their buoyancy, but the longer ones move faster, spreading them out by length. Photos (r.) shows a typical sample at the start and after 94 hours of spinning at 1257 radians per second (roughly 12,000 RPM). Credit: NIST

Spin Control: New Technique Sorts Nanotubes By Length

Researchers at the National Institute of Standards and Technology (NIST) have reported a new technique to sort batches of carbon nanotubes by length using high-speed centrifuges. Many potential applications for carbon nanotubes depend on the lengths of these microscopic cylinders, and one of the most important features of the new technique, say the scientists, is that it should be easily scalable to produce industrial quantities of high-quality nanotubes.

The role of surfactants in carbon nanotube toxicity

(Nanowerk Spotlight) Synthesized carbon nanotubes, especially single-walled carbon nanotubes (SWCNTs), are in the form of bundles with other impurities such as catalyst particles and amorphous carbon debris. In order to be useful for many types of applications, for instance in nanoelectronic devices or biomedical applications, SWCNTs need to be purified and dispersed into individual nanotubes. One method to do this is by surfactant stabilization of the hydrophobic nanotube surface, which overcomes the van der Waals forces among the nanotubes and results in suspensions of individual SWCNTs.

The hot new nanotech: testing chillies

How hot is hot? When it comes to chilli peppers, the answer tends to be subjective — even official hotness ratings are based on the reliability of human testers or expensive high-tech machines. But now nanotubes may provide an objective, and cheap, check on how hot that sauce you’re ladling onto your kebab is.
