KentuckyFC writes "Scientists have found a way to join buckyballs together so that they form buckywires. The wires form when buckyballs are dissolved in an aromatic hydrocarbon called 1,2,4-trimethylbenzene. The solvent links the balls together to make wires shaped like a string of pearls, which then precipitate out. This relatively simple procedure opens the door to industrial-scale manufacture. Buckywires ought to be efficient light harvesters because of their great surface area and the way they can conduct photon-liberated electrons. But perhaps the area of greatest interest is drug delivery. The researchers suggest that buckywires ought to be safer than carbon nanotubes because the production method is entirely metal-free. This contrasts with the production of nanotubes, which are formed in a reaction catalyzed by metallic nanoparticles."
