We demonstrate a multiplex plasmonic anti-counterfeiting platform by embedding multiple molecules on a single substrate with superior nanometer scale spectral and spatial resolution. The encoded specific molecular information can be read out only using Raman spectroscopy. Multiplexing increases the...
