Applied DNA Sciences, a leader in Polymerase Chain Reaction (PCR)-based DNA manufacturing for product authenticity, traceability solutions, nucleic acid-based biotherapeutic development and liquid biopsies, today announced that the UU Patent and Trademark Office (USPTO) has granted it United States patent no. 10,519,605 entitled Methods of Marking Cellulosic Products.

The newly issued patent covers methods of tagging man-made cellulosic (MMC) fibres or materials with a nucleic acid (DNA) tag during production and later authenticating the nucleic acid-tagged MMC fibers and/or materials via PCR-based detection techniques to confirm provenance and or authenticity.
According to the company, global MMC production volume more than doubled from 3 million (in 1990) to 6.7 million metric tons in 2018, and is expected to continue to grow at an annual rate of 9% through 2024. MMCs include viscose, Rayon, acetate, lyocell, Tencel, modal and cupro materials.
“Most MMCs are primarily derived from wood. Heightened awareness related to the sourcing of wood raw materials from endangered or ancient forests, the social and environmental concerns relating to the chemicals used in production, as well as the amount of energy and water used to manufacture MMCs, has led to greater oversight of the MMC industry and requires proof that these materials come from controlled and sustainable sources that can be verified by scientific evidence,” Applied DNA said.
