Marking material
A material for indelibly and uniquely marking an article for identification purposes includes a mixture including between about 1% and 10% by weight fluorescent identifier, DNA, and the remainder including predominantly a solvent.
1. An article for indelibly and uniquely marking an article for identification purposes, the article comprising:
a mixture having between about 0.1% and 10% by weight of a fluorescent identifier, a DNA, solvent and a propellant, said mixture being provided in a pressurized container which has one or more nozzles from which said mixture is dispersable as an aerosol, wherein said container is pressurized to a pressure greater than 60 p.s.i., and wherein said propellant disperses said mixture as the aerosol of fine particles each having a diameter of between 40 μm and 70 μm, said mixture having at least 10 15 DNA molecules per liter.
2. The article of claim 1 , said container being pressurized to a pressure of approximately 75 p.s.i.
3. The article of claim 1 , each of said particles having a diameter of approximately 50 μm.
4. The article of claim 1 , said mixture having between 25% and 26% by weight of said propellant.
5. The article of claim 1 , said propellant being dimethyl ether.
6. The article of claim 1 , said mixture having between 0.5% and 5% by weight of said fluorescent identifier.
7. The article of claim 6 , said mixture having approximately 1% by weight of said fluorescent identifier.
8. The article of claim 1 , said fluorescent identifier being detectable by ultraviolet light.
9. The article of claim 1 , said DNA being biosynthesised.
10. The article of claim 1 , said DNA being uniquely encoded.
11. The article of claim 1 , said DNA having an identifiable unique sequence therein.
12. The article of claim 1 , said DNA being uniquely coded with chemical taggants.
13. The article of claim 1 , further comprising a molecular carrier, said DNA and said molecular carrier being between 9% and 10% by weight of said mixture.
14. The article of claim 1 , said mixture having approximately 3×10 17 DNA molecules per liter.
15. The article of claim 1 , said mixture having a preservative.
16. The article of claim 15 , said preservative being sodium benzoate.
17. The article of claim 15 , said preservative being between 0.1% and 3% by weight of said mixture.
18. The article of claim 1 , said solvent being water.
19. The article of claim 1 , said mixture containing an overt material with a visible and durable stain.
20. The article of claim 19 , said stain being erythrosine.
21. The article of claim 19 , said stain being between 0.1% and 10% by weight of said mixture.
22. The article of claim 21 , said stain being 1% by weight of said mixture.
23. The article of claim 1 , said propellant pressurizing said container.
24. An article for indelibly and uniquely marking an article for identification purposes, the article comprising:
A mixture having between 0.1% and 10% by weight of a fluorescent identifier, DNA and a remainder of the mixture being predominately a solvent, said mixture being provided in a pressurized container having a propellant therein which has one or more nozzles from which said mixture is dispersable as an aerosol wherein said pressurized container is pressurized to a pressure of greater than 60 p.s.i., wherein said aerosol has particles each having a diameter of between 40 μm and 70 μm, said mixture having at least 10 15 DNA molecules per liter.
