Surface-enhanced Raman spectroscopy (SERS) using Ag nanoparticle films produced by pulsed laser deposition

► Pulsed laser deposition (PLD) produces silver nanoparticle films. ► These films can be used for surface-enhanced Raman spectroscopy (SERS). ► Commercial film shows good SERS reproducibility but poor signal intensity. ► PLD shows a good SERS response coupled with good reproducibility.
