Nanomaterials synthesis and integration: market-ready anti-counterfeiting

Nanomaterials synthesis and integration

Published on 7 May 2019

Liten researchers are tackling brand protection and product authentication technologies and, most notably, the insertion of unique optical codes in materials. A startup, Naomarq (an Alcen subsidiary), was created to commercialize some of our novel and effective anti-counterfeiting solutions. Today, a team of Liten researchers has been assigned to synthesizing markers exclusively for Naomarq to meet the unique requirements of the market segments and materials—metal, plastic, textile, and paper—the company addresses. The technology is based on mineral, organic, or organometallic particles that emit light when excited. The light emitted is characterized by a complex spectrum, which serves as the optical code. Our researchers synthesize particles whose complex emission codes are completely controllable and that can be authenticated using a simple reader. This process involves several steps:

  • The particles are synthesized

  • The stability of the optical code is checked in given measurement conditions

  • The particles are integrated into the product a manufacturer wishes to mark or authenticate either during or post-process

  • The integrity of the original material is checked and the stability of the solution developed is measured

Our solutions can be integrated into a manufacturer’s processes. Depending on the situation, we can conduct verification tests on samples in the lab, or—for instances where the solution is integrated into the material before manufacturing—directly on “marked” products coming off a manufacturer’s production line. Testing on manufactured products is useful when the materials used to manufacture the product must be blended with the particles that generate the optical code, for example. 

We have developed an extensive range of coded particles and continue to add new ones as new applications arise. Our solutions can meet a broad range of product requirements, from UV and temperature resistance (500 °C to 1,000 °C in some cases) to inkjet printing and liquid- and solid-phase processes. A variety of readers are also available, ensuring a fast, accurate response regardless of the authentication solution used. Finally, we have developed several code implementation lines available for transfer to manufacturers.

Liten’s approach to anti-counterfeiting technology is to overcome current limitations such as temperature and moisture and to integrate the technology to encourage widespread adoption by manufacturers of all kinds. A key factor in the success of these solutions will be to ensure that they have the least possible impact on manufacturers’ existing processes. We are currently in the final stages of negotiations on several contracts with manufacturers—evidence that the solution does address an actual market need.

  • Compatible with all types of materials

  • A mature technology ready for rollout on a variety of markets

  • Custom solutions can be developed for specific manufacturer needs; the codes are the exclusive property of the manufacturer


  • Around ten researchers assigned exclusively to anti-counterfeiting research

  • ​Around ten patents filed since 2011
