Anti-counterfeiting SERS security labels derived from silver nanoparticles and aryl diazonium salts

Abstract

The development of anti-counterfeiting inks based on surface-enhanced Raman scattering (SERS) labels have attracted great interest in recent years for their use as security labels in anti-counterfeiting applications. Indeed, they...

Raman encoding for security labels: a review

“…31 Li et al developed an inkjet printing ink based on silver nanoparticles (Ag NPs) functionalized by aryl diazonium salts, which were then inkjet printed on a polyethylene naphthalate substrate. 32 The successful implementation of these cases effectively proves the combination of inkjet printing and Raman-active materials, thanks to the excellent ink compatibility of inkjet printing. And with the development of material synthesis technology, Raman-active materials have become more adaptable to a variety of application environments.…”
