Title
(EN) DENDRITIC TAGS
(FR) MARQUEURS DENDRITIQUES
Abstract
(EN)
Preparing a dendritic tag includes forming a liquid composition including dendrites, separating the dendrites from the liquid composition, and disposing the dendrites on a substrate. In some cases, the composition is applied to a substrate and the liquid is evaporated to yield at least one dendrite in direct contact with the substrate. A labeled item includes an item and a dendritic tag coupled to the item, such that the item can be identified or authenticated based on a property of the dendritic tag.
(FR)
L'invention concerne la préparation d'un marqueur dendritique comprenant la formation d'une composition liquide qui contient des dendrites, la séparation des dendrites de la composition liquide, et la disposition des dendrites sur un substrat. Dans certains cas, la composition est appliquée sur un substrat et le liquide est évaporé pour produire au moins une dendrite en contact direct avec le substrat. Un article marqué comprend un élément et un marqueur dendritique couplé à l'article, de sorte que l'élément peut être identifié ou authentifié sur la base d'une propriété du marqueur dendritique.
