Title (EN) NANOPARTICLES-BASED TAGGANT SYSTEMS AND METHODS
(FR) SYSTÈMES ET PROCÉDÉS DE TRACEUR BASÉ SUR DES NANOPARTICULES
Abstract:
(EN) Coding systems may include an object and a taggant linked to the object, the taggant comprising one or more types of phase change nanoparticles, each type of phase change nanoparticles having a phase change temperature different from a phase change temperature of other types of phase change nanoparticles, wherein, when the taggant is thermally scanned, different phase change temperatures result in one or more predefined melting peaks forming a code that represents information particular to the object.
(FR) Systèmes de codage pouvant comprendre un objet et un traceur lié à l'objet, le traceur comprenant un ou plusieurs types de nanoparticules à changement de phase, chaque type de nanoparticules à changement de phase ayant une température de changement de phase différente d'une température de changement de phase d'autres types de nanoparticules à changement de phase ; quand le traceur est thermiquement balayé, différentes températures de changement de phase entraînent un ou plusieurs pics de fusion prédéfinis formant un code qui représente des informations propres à l'objet.
