In recent years, the possible applications for double-walled carbon nanotubes have excited scientists and engineers, particularly those working on developing renewable energy technologies. These tiny tubes, just two carbon atoms thick, are thin enough to be transparent, yet can still conduct electricity. This combination makes them well-suited for advanced solar panels, sensors and a host of other applications

Owing to the novel properties of carbon nanotubes, a series of problems associated with in vitro toxicity assessments of carbon nanotubes have appeared in a lot of literature. In order to properly evaluate the potential risk to human health, the cell toxicity assay of carbon nanotubes can not be conducted by traditional methods employed in common toxicology.

It's hard to study something with any rigor if the subject can't be produced uniformly and efficiently. Researchers who study double-walled carbon nanotubes find themselves in just this predicament. The problem is that current techniques for synthesizing double-walled carbon nanotubes also produce unwanted single- and multi-walled nanotubes. Northwestern University researchers now offer a clever solution: They used a technique called density gradient ultracentrifugation to cleanly and easily separate the double-walled nanotubes from the undesirables.
