2018年1月1日 · This research reveals a new road to solve the aggregation issue of traditional liquid SERS and start a routine to enhance the sensitivity of SERS-active composite by using hybrid rGO-Au@AgNRs for material analysis and environment pollution.

2021年1月1日 · The SERS substrates based on graphene, graphene oxide (GO) and reduced graphene oxide (rGO) have attracted lately much attention because of their distinct physical properties. In order to achieve highly effective SERS substrates we used solid GO and rGO films deposited on a polymeric substrate, on which colloidal Ag nanoparticles (AgNPs) have ...

2024年5月16日 · Ag/rGO composite substrate possesses superior SERS performance with an ultralow detectable concentration of 4-aminothiophenol (10−10 M) and good reproducibility, endowing the material with a better enhancement effect than pure Ag nanoparticles.

2024年4月27日 · Functionalizing rGO induces defect states (sp3), increasing NLO response. Cu, Ag, and Au exhibit higher Surface-Enhanced Raman Scattering (SERS) activity due to rGO-induced structural modifications. SERS signals are influenced by …

Surface-enhanced Raman scattering (SERS) is a rapid and promising detection technique for trace molecules. A central goal of research in this area is to achieve the highly sensitive detection of molecules built on a systematic understanding of enhancement mechanisms. Herein, we develop a Ag cluster@rGO compo
