Turning to nature to fight counterfeiting
Applied DNA Sciences Inc. (ADNAS) has wrapped up trials demonstrating that its SigNature DNA markers can be authenticated when used in packaging materials and on pharmaceutical tablets. The markers were added to new pharmaceutical-grade inks produced in partnership with Nissha Printing Company and KishuGiken Kogyo Co. Ltd. (KGK).
ADNAS is hoping to “secure supply chains by preventing the incursion of counterfeits,” Dr. James Hayward, President and CEO, ADNAS, tells PMP News. “We engineer unique DNA tags from botanical genomes and can produce and manufacture an infinite quantity depending upon demand.” (Sister publication Packaging Digest interviewed Hayward in 2014 about the technology and its potential.)
With the DNA-based solution, there may be more options for encryption compared with digital coding. Digital codes are “binary,” meaning they have two choices for each bit of content, explains Hayward. DNA offers four choices—the squared of binary, he says.
