Applied DNA Sciences has been granted a US patent that protects its CertainT molecular tagging process in relation to man-made cellulosic fibres and materials.

The newly-issued 10,519,605 patent, entitled ‘Methods of Marking Cellulosic Products’, covers methods of tagging man-made cellulosic (MMC) fibres or materials with a nucleic acid (DNA) tag during production. It also covers later authenticating the nucleic acid-tagged MMC fibres and/or materials via PCR-based detection techniques to confirm provenance and/or authenticity.
