Abstract

Herein, we present the first example of a silicon nanoshuttle-based security ink simultaneously featuring attractive optical and magnetic properties, suitable for fluorescent and magnetic anti-counterfeiting and encryption. Significantly, the information can be dual-encrypted through multi-color fluorescence and longitudinal (T1)/transverse (T2) relaxation contrast by using the silicon nanoshuttle-based security ink. We further demonstrate the feasibility of this high-performance ink for practical application in banknote anti-counterfeiting.
