Abstract

Excellent and recyclable surface-enhanced Raman scattering substrates were fabricated via a one-step route: reducing gold ions to Au nanoparticles with silicon–hydrogen bond and assembling them in-situ on the Si wafer. Gold nanoparticles with the average size of 22 nm were epitaxially grown and uniformly assembled. The substrate exhibited excellent surface-enhanced Raman effect in the low concentration detection (1 × 10− 10 M) of Rhodamine 6G with relative standard deviation of
