  • System and method for authentication and tamper detection using nucleic acid taggants
    Patent number: 10513735
    Abstract: A method for authenticating an item of interest. A nucleic acid tag comprised of a nucleotide-support platform attached to a first nucleic acid molecule is added to the item of interest, where information about the item of interest is contained within the first nucleic acid molecule. A portion of an item is sampled for the presence of the nucleic acid tag, where the item is potentially the item of interest. The presence of the nucleic acid tag is detected in the sample, where the presence of the first nucleic acid tag authenticates the item as the item of interest.
    Type: Grant

  • System and method for authentication and tamper detection using nucleic acid taggants
    Patent number: 9243283
    Abstract: Methods for authenticating and/or detecting tampering of an item of interest using a nucleic acid tag. A nucleic acid tag comprising a nucleotide-support platform attached to a nucleic acid molecule is created or obtained and then sealed within or on the item of interest. The surface of the item of interest is sampled for the presence of the seeded tag after the item of interest has been moved from one location to another or has been stored for a period of time, during which tampering can occur and/or authentication may necessary. The presence of the tag can indicate that tampering has occurred, or that the item of interest is authentic.

  • Use Of Diatomaceous Earth As The Base Substrate For Nucleic Acid Tags
    Publication number: 20140155272
    Abstract: A nucleic acid tag comprising: a nanoparticle nucleotide-support platform attached to a plurality of nucleic acid molecules, each of said nucleic acid molecules comprising identifying information, with a spacer located between the nanoparticle nucleotide-support platform and the identifying information, and where the nanoparticle nucleotide-support platform comprises diatomaceous earth; and an encapsulant surrounding the nanoparticle nucleotide-support platform.
