Dual‐Coded Plasmene Nanosheets as Next‐Generation Anticounterfeit Security Labels

Plasmene nanosheets are demonstrated as the next-generation dual plasmonic and surface-enhanced Raman scattering (SERS) coded anticounterfeit security label for banknotes. Engineering the morphologies of plasmene-constituent nanoparticles and varying of SERS molecular labels offer virtually unlimited coding capacities.
