Researchers have coopted DNA for a non-biological use -- sorting carbon nanotubes. A new linkurl:study;http://www.nature.com/nature/journal/v460/n7252/abs/nature08116.html reports that synthetic DNA molecules can form paper-like sheets that can be used to separate nanotubes of different diameters, lengths, chiralities, and electronic properties. The study reveals some of "the richness of the structural motifs that nucleic acids may have," said Ming Zheng, a biochemist and materials scientist at
