“…In addition, to examine the reliability of the Au-NP substrates, the Raman spectra of RB and MG with lower concentrations (10 −8 and 10 −9 M) adsorbed on four Au-NPs substrates were also examined, and the corresponding Raman spectra are shown in figures 4(b) and (c), respectively. It is known that the characteristic peaks of RB and MG with concentrations down to 10 −9 M can be distinguished clearly [32,33]. These measurement results indicate that the fabricated Au-NP substrates have excellent activity and reliability for SERS applications.…”

Au-nanoparticle (Au-NP) substrates for surface-enhanced Raman spectroscopy (SERS) were fabricated by grid-like scanning a Au-film using a femtosecond pulse. The Au-NPs were directly deposited on the Au-film surface due to the scanning process. The experimentally obtained Au-NPs presented local surface plasmon resonance effect in the visible spectral range, as verified by finite difference time domain simulations and measured reflection spectrum. The SERS experiment using the Au-NP substrates exhibited high activity and excellent substrate reproducibility and stability, and a clearly present Raman spectra of target analytes, e.g. Rhodamine-6G, Rhodamine-B and Malachite green, with concentrations down to 10 M. This work presents an effective approach to producing Au-NP SERS substrates with advantages in activity, reproducibility and stability, which could be used in a wide variety of practical applications for trace amount detection.

Rhodamine B Detection by SERS with Urchin-like Gold Nanostructures in Water Solution

Abstract: In this work, urchin-like gold nanostructures obtained by a seed-mediated method, were coated with silica and analyzed as substrates to detect low concentrations of Rhodamine B in water solution, obtaining promising results for SERS applications.
