TECHNOLOGY | ANTI-COUNTERFEITING


Molecular taggants Meanwhile, Applied DNA Sciences (ADNAS), a provider of DNA-based anticounterfeiting and authentication technologies, received new patents in October 2017 for its SigNature T molecular taggants and its Multimode Image and Spectral Reader (MMR). The handheld MMR device detects one or more taggants and compares them to a library for authentication. Applied DNA is using its CertainT supply chain platform to track the origin of components throughout the supply chain. In addition to proving a product is not a counter-

court cases by providing a reliable authentication method, while laser marking replaced the more complex method of marking with direct or indirect hot stamp foil and ink. TruTag, which offers a covert marker technology based on nano-porous silica, has been focusing recently on adding markers to individual pharma- ceutical tablets and capsules (because silica has GRAS status with the US FDA, the taggants are edible). However, the company’s taggants can also be added to packaging and to food. In August, TruTag announced a parternship with Hongyang Biotechnology, an animal health management and farm management solution provider to the live- stock sector in China, to develop authentication through direct marking of livestock and meat packaging.

items feasible, says the company, because the tag can be read with an optical reader and can be coded with information such as product, manufac- turing line and batch. The company’s latest low- cost optical reader device – the Handheld Hyper- spectral Imager – won a 2017 Prism Award in the Imaging and Cameras category from the interna- tional optics and photonics society SPIE. The device is claimed to be the first to capture a multi-megapixel hyperspectral datacube without requiring external processing. The cloud-connect- ed device delivers images in 400 colours and allows users to select acquisition wavelengths, the company says. Proprietary taggants from SICPA are incorpo-


rated into Clariant masterbatches or compounds for the pharmaceutical packaging and medical device markets, the two companies announced last year. The PLASTIWARD programme includes a tailored security system design, deployment, and ongoing performance monitoring, say the companies.

feit, the CertainT technology can also be used to verify the origin of components and two textile companies are currently using it to show that their textiles are made from recycled PET. “Consumers are becoming increasingly concerned with protect- ing the environment as well as demanding more information about the impact, origin, and authen- ticity of their products,” says Dr James A Hayward, President and CEO of Applied DNA Sciences. “Our solution enables brands to provide consumers with certainty in knowing their recycled products are forensically authenticated from source to shelf.” Techmer PM, in an ongoing partnership with Applied DNA, compounds the SigNature T DNA molecular tags into Techmer PM polyester formula- tions, which it supplies to Palmetto Synthetics for producing specialty synthetic fibers. The Techmer PM formulation is a component of a system of solutions for fibre including colours and additives used by Palmetto. Palmetto’s fibres, which include polyester, nylon, and others, are used in apparel, automotive, and industrial applications. The taggant ensures traceability and supply-chain transparency, safeguarding against product recalls and liability. The Verimaster system from Addmaster (UK) is
