A Permanent and Environmental Stable Marking System for Leather-Traceability via Encapsulated DNA

摘要：

Native DNA is unstable under the predominant conditions during the leather production. To establish a new marking system for leather based on DNA, encapsulated DNA was integrated into a conventional basecoat. It was shown that this marking system can be readout from the finished leather. In addition, the stability of the capsules under extreme acidic conditions shows a satisfactory extent for the tanning process, which takes at most four days. Also a protection of the capsule DNA against sunlight radiation could be shown.
