Dna marking of previously undistinguished items for traceability

摘要: The invention provides a method of marking an item with naturally-derived or synthetic non-natural polymeric marker molecules, such as DNA Peptide in conjunction optional visible rapid scan reporters for authenticating tracking, which the includes providing marking, and applying medium including to item. further methods stably binding immobilizing activated deoxyribonucleic acid onto objects substrates. exposing alkaline conditions, contacting object substrate. Also provided are increasing recoverability taggants from object. include steps incorporating taggant into solution; mixing solution perturbant form first polymer second at least portion taggant-coated also marker, molding provide all part encodes information unique and/or model desired.
