摘要：
A method of using at least one nanoparticle for an anti-counterfeit application including selecting the at least one nanoparticle having a non-spherical configuration; providing the at least one nanoparticle on a substrate; providing a light to the at least one nanoparticle; determining a position of the at least one nanoparticle based on providing the light to the at least one nanoparticle; determining a color of the at least one nanoparticle based on providing the light to the at least one nanoparticle; defining a nanofingerprint based on the position and the color of the at least one nanoparticle; and recognizing the nanofingerprint.
