Ohio State University researchers have invented a process for uncoiling long
strands of DNA and forming them into precise patterns. Ultimately, these DNA
strands could act as wires in biologically based electronics and medical devices,
said L. James Lee, professor of chemical and biomolecular engineering at Ohio
State University. In the early online edition of the Proceedings of the National
Academy of Sciences, Lee and postdoctoral researcher Jingjiao Guan describe
how they used a tiny rubber comb to pull DNA strands from drops of water and
stamp them onto glass chips.
