Researchers from CNRS  and the Université de Strasbourg - France , headed by Nicolas Giuseppone  and Bernard Doudin, have succeeded in making highly conductive plastic fibers that are only several nanometers thick. These nanowires, for which CNRS has filed a patent, "self-assemble” when triggered by a flash of light.

 Inexpensive and easy to handle, unlike carbon nanotubes (3), they combine the advantages of the two materials currently used to conduct electric current: metals and plastic organic polymers (4). In fact, their remarkable electrical properties are similar to those of metals.
