Multidimensional SERS Barcodes on Flexible Patterned Plasmonic Metafilm for Anticounterfeiting Applications

A multidimensional surface-enhanced Raman scattering (SERS) barcode is developed on patterned flexible plasmonic metafilm. The facile adjustment of barcodes in conjunction with the choices of Raman probes gives rise to an unlimited coding capacity and a high security level of our SERS barcoding system. Together with the excellent mechanical robustness and stability of the obtained metafilm, it is highly promising for next-generation advanced security solution.
