Nanotubes that Form 'Nanocarpets'

Roland Piquepaille writes "By mixing a salt compound with an hydrocarbon, researchers at the University of Pittsburgh have created molecules able to sense their environment. Then they used these molecules to develop self-assembling nanotubes which look like that 'nanocarpets'. These nanostructures can change colors when their environment is modified and can be trained to kill bacteria, such as E. coli. Now, they plan to develop products that would both detect and destroy biological weapons. Read more for selected excerpts about these nanostructures acting as biosensors."
