SICPA and UbiQD Partner for Quantum Dot Security

Swiss-based SICPA and New-Mexico nanotechnology company UbiQD have announced an expansion of their partnership to develop security inks based on the latter’s quantum dot technology.

Quantum dots (QDs) are semiconductor nanoparticles that exhibit high efficiency photoluminescence over a wide range of tunable colors, making them effective at imparting unique optical properties. As a result, security features based on QDs are inherently very difficult to reproduce and can be used to combat counterfeiting and strengthen security applications, said SICPA.

The two companies have been co-developing QD-based security features for the past six years. Having completed a number of technical milestones in a multi-phased joint-development effort, UbiQD and SICPA are now expanding their partnership to commercialise several security applications based on the novel characteristics of UbiQD’s technology through an exclusive supply and licencing agreement.
