Purdue creates self-generating nanotubes with 'dial-up' properties

eam discovered some unexpected behaviors their nanotubes exhibit.

"We have found that the nanotubes promote their own formation," Fenniri said. "Such behavior is very reminiscent of living systems, in that they replicate and adapt to their environment."

Realizing that their homegrown nanotubes catalyze their own formation opened a whole new field of research for the team. They found that by placing the raw materials from which nanotubes form into a test tube, then adjusting such conditions as temperature and pressure, the nanotubes could organize themselves into one of many different configurations, several never seen previously.

"You could imagine that one type of nanotube forms at 25 degrees Celsius, but another type with very different physical and chemical properties would form at 70 degrees," Fenniri said. "That's a simplification, of course, but it illustrates the principles we have uncovered."

The relative ease of manipulating the properties of nanotubes makes Fenniri optimistic that many new applications will be possible. One possibility is to use the nanotubes in disease treatment.

"Many drugs destroy infectious bacteria by poking holes in their cellular membranes and leaking out their nutrients, just like pricking a hole in a balloon," he said. "Our nanotubes could also act in this manner, but in addition, they have the ability to lure the bacteria with a bait that guides them to the cell membrane where they can start destroying the cell."

Further exploitation of the tubes' dial-up properties could lead to nanotubes that conduct electricity or photons, making them useful in computer memory systems, high-definition displays, biosensors and drug delivery systems. Fenniri is hopeful the findings will prove beneficial in many fields.

"Nanotechnology relies on our ability to control the behavior of matter at the molecular scale," he said. "The versatility and robustness of our system is already point
