Counterfeiters needn't apply here. Applied DNA Sciences makes anti-counterfeiting and product authentication solutions. Its products are encoded with botanical DNA sequences that can distinguish counterfeits from the genuine article. The DNA markers (which hold the SigNature DNA brand) can be employed in ink, glue, holograms, microchips, and paint, and are then used to tag documents, currency, event tickets, and clothing labels. The company applies its SigNature markers to art and collectibles, fine wine, consumer products, digital recording media, pharmaceuticals, and homeland security products.
