Patent

CA 2321838

A method for marking or tagging individual microparticles using a near infrared fluorophore for identification is provided. The near infrared fluorophore is included with one or more layers comprising the microparticle. Desirably, the coating layers contain colorants such as dyes and/or pigments which increases the total possible combinations that may be used to identify the marked material. There is further provided a method for marking a material using these microparticles containing a near infrared fluorophore.

L'invention concerne un procédé de marquage et d'étiquetage de microparticules individuelles au moyen d'un fluorophore dans le proche infrarouge à des fins d'identification. Ce fluorophore dans le proche infrarouge est compris dans une ou plusieurs couches formant les microparticules. De préférence, les couches de revêtement renferment des colorants tels que des matières tinctoriales et/ou des pigments qui augmentent le nombre total de combinaisons possibles pouvant être utilisées pour identifier le matériel marqué. L'invention concerne également un procédé de marquage d'un matériel à l'aide de ces microparticules renfermant un fluorophore dans le proche infrarouge.
