SigNature® DNA is the core of our technology platform. Based on botanical DNA, our precision-engineered marks have not and cannot be broken. The conventional process used to sequence (“decode”) native DNA is not possible with the engineered mark. Additional layers of protection and complexity are added to the mark in a proprietary manner.


This botanically engineered solution is shielded by a portfolio of over 100 patents, patent applications and trademarks. With essentially infinite variability, individualized custom DNA sequences can be created and embedded into a range of host carriers such as ink, varnish, thread, laminates and metal coatings. Highly secure, robust, durable and cost-effective, SigNature DNA markers can be used as a forensic complement to barcodes, watermarks, holograms, RFIDs, microdots or any other security platform.

SigNature DNA in Action


Absolute verification of source, authenticity and provenance.

The SigNature DNA platform has proven highly resistant to UV radiation, heat, cold, vibration, abrasion and other extreme environmental conditions, and a single SigNature DNA mark will support several authentications in its lifetime. Unsurpassed durability, accuracy and assurance make SigNature DNA markers an ideal foundation or enhancement for any security effort.

Manufacturers, brands, and other stakeholders can ensure their raw materials and products are protected, product claims are authentic and customer expectations are met.

DNA is nature’s indisputable determinant of truth


To ensure that a product is authentic, we recommend regular audits and authentication of products throughout the supply chain. ADNAS can customize an authentication program that best fits your goals and needs.

ADNAS offers full forensic authentication services in our Stony Brook, NY laboratory. Additionally, our SigNify® on-site authentication provides rapid in-field authentication of samples.
