University of Pittsburgh researchers have synthesized a molecule that forms the first “nanocarpet,” whereby the nanotubes organize themselves into an expanse of upright clusters that looks like the fibers of a shag rug. Moreover, unlike other nanotube structures, these tubes can sense their environment, change color and can be trained to kill bacteria.

The research aims at developing a paint that in the event of biological or chemical agents being deployed would change color and simultaneously destroy the deadly substances.
