Abstract (en)
[origin: WO2006009810A1] Aspects of the invention provide stabilized light-sensitive compounds and methods for their use in product authentication and/or monitoring. A light sensitive compound, such as a fluorescent dye, is combined with an isolating material to form a liquid mixture. The mixture is applied onto the surface of a solid base. The isolating material isolates the light sensitive compound from adverse environmental effects and serves to control the rate of hydration of the light sensitive compound. Preferably, liquid samples are authenticated with the stabilized light sensitive compound.
