Dipping into a drink: Basil-seed supported silver nanoparticles as surface-enhanced Raman scattering substrates for toxic molecule detection

High-density plasmonic Ag nanoparticles (Ag-NPs) have been synthesized on the three-dimensional framework of natural basil-seeds as the inexpensive substrates for portable surface-enhanced Raman scattering (SERS) detection and SERS sensor.
