Abstract
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.
