A new strategy to prepare surface-enhanced Raman scattering-active substrates by electrochemical pulse deposition of gold nanoparticles.
In this communication, we develop a simple pathway to prepare SERS-active substrates with Au nanoparticles (NPs) by an electrochemical strategy of deposition-dissolution cycles (DDCs). The prepared SERS-active substrates demonstrate large Raman scattering enhancement for Rhodamine 6G (R6G) with a detection limit of 2 × 10(-12) M and an enhancement factor of 5.8 × 10(7).
