Hybrid Au@Ag core–shell nanoparticles on anodic aluminum oxide for surface-enhanced Raman scattering

Key Points

• Enhanced signals from surface-enhanced Raman scattering were observed using core-shell nanoparticles.
• The significant improvement was attributed to the plasmonic properties of hybrid Au@Ag nanoparticles.
• Assessment involved nanomaterials deposited on anodic aluminum oxide substrates for optimized performance.
• Results indicate potential for better detection methods, yet further studies are needed for practical applications.
