Abstract: An ink containing a small amount of peptide nucleic acid is provided to identify authenticity of a peptide nucleic acid in a matter printed with the ink while realizing improved durability of the ink. A printing ink comprises 0.000007-0.02 wt% of peptide nucleic acid for identifying authenticity. In a variant, a paint or coating solution comprises 0.000007-0.02 wt% of peptide nucleic acid for identifying authenticity. To detect peptide nucleic acid for identifying authenticity in a product using the printing ink, paint or coating solution, the peptide nucleic acid(PNA) is contacted with a PNA chip, in which a single spiral PNA complementary to the PNA and one to three optional single spiral PNAs are integrated, and then with a phosphor.

Abstract: A forgery preventive functional fiber is provided to mix the specific pigment into the complex fiber with a side-by-side type, thereby displaying the functionality. A first and a second components as the synthetic polymer chip are heated, mixed and spun so that the forgery preventive functional fiber is manufactured. The forgery preventive functional fiber is dyed by the specific pigment. Polyester, nylon, polypropylene, polyethylene and polyurethane are used as the mixing polymer of the first component and the second component. The same polymer or different mixing polymers are used as the mixing polymer of the first and second components according to the mixing property of the specific pigment. Colored pigment, fluorescent pigment, infrared pigment and the like are used as the specific pigment and added differently to the first and second components so that various effects are represented.
