Printable Surface Enhanced Raman Scattering (P-SERS) silver substrates were used with Metrohm Raman’s Mira DS handheld Raman analyzer to successfully detect heroin in 18 crude street heroin samples. Detection of heroin with P-SERS was accomplished easily and very quickly, with minimal sample clean-up. Solvent studies were also implemented to determine the optimal solvent for crude sample extraction, with results included here.
