ABSTRACT:
An identifiable code pattern, a method of providing a carrier material with an identifiable code pattern, and a method for detecting an identifiable code pattern are based on applying water-soluble nanocrystals to carrier materials in a spatially arranged format that can be detected by exposing the identifiable code pattern to an excitation light source in exciting the water-soluble nanocrystals, and detecting any fluorescence peaks emitted from the excited water-soluble nanocrystals using a detection system.
