 Scientists have great interest in the optical properties of single-walled carbon nanotubes (SWCN), but the random orientation of the nanotubes has made measurement difficult. Now researchers have developed a method for orienting SWCNs. They first wrap them in DNA to retard clumping, then disperse them in a polymer. Heating and stretching the polymer aligns the nanotubes to permit optical characterization.
