Scientists and engineers report a new method of disentangling carbon nanotubes from a mixture and purifying them into separate species of the same electronic type. More than 20 short DNA sequences, researchers say, have the ability to recognize CNT species and fold selectively onto the nanotubes. Their hypothesis: DNA recognizes a specific nanotube in the same way that biological molecules recognize each other by structure.
