New ‘Alien Nanofiber’ Has Potential Anti-Counterfeiting Applications

Carlos Rinaldi, assistant professor of chemical engineering at the University of Puerto Rico, has created 150-nanometer fibers that can be placed inside a garment or paper document and serve as a “fingerprint” that proves the garment or document is genuine.

The fibers contain nanoparticles with an electrical, magnetic or optical signature that can prove a product genuine if scanned by a device looking for the particular signature.
