Purdue researchers use enzyme to clip 'DNA wires'

ns, or millionths of a meter, and 2 nanometers wide," Kinsella said. "When coated with particles and fragmented by the enzyme, we were able to distinguish that the once-single DNA wire was clipped into smaller wires."

In future work, the Purdue researchers plan to stretch DNA coated with magnetic particles between electrodes and test the coated genetic material for electrical properties.

The research is funded by the National Aeronautics and Space Administration through Purdue's NASA Institute for Nanoelectronics and Computing. The institute is a collaboration of six universities led by Purdue, whose director is Supriyo Datta, the Thomas Duncan Distinguished Professor of Electrical and Computer Engineering at Purdue. The work also is affiliated with the Birck Nanotechnology Center and the Bindley Bioscience Center in Purdue's Discovery Park, the university's hub for high-tech research.
