Research Overcomes Key Obstacles to Scaling ­p DNA Data Storage

North Carolina State University (NC State) researchers have created new techniques for labeling and retrieving data files in DNA-based information storage systems, overcoming two key obstacles to widespread adoption of DNA data storage technologies.

The challenges are how to identify the strands of DNA that contain the correct file, and once those strands are identified, how can they be removed so they can be read without destroying them.

The researchers addressed these problems with two techniques together called DNA Enrichment and Nested Separation (DENSe).

NC State’s Kyle Tomek said the two techniques “when used in tandem, open the door to developing DNA-based data storage system with modern capacities and file-access capabilities.”

Added NC State’s James Tuck, “Next steps include scaling this up and testing the DENSe approach with larger databases.”
