Metallic silver-gold nanoparticles (1–5 nm) encapsulated into carbon nanospheres (20–30 nm), or carbon flakes and flowers were synthesized via laser-induced chemical liquid phase deposition. The obtained carbon-silver-gold nanostructures are characterized by high specific surface area and demonstrated high sensitivity as a material for surface-enhanced Raman scattering and adsorption properties allowing analyte extraction from a dilute solution for quantitative monitoring of low concentration components.
