2019年6月1日 · In the present work, we fabricated and demonstrated a generic SERS sensor based on Ag-rGO composite to detect at least three different analytes simultaneously. It has been shown that decoration of spherical silver nanoparticles on the rGO nanosheets can be achieved by a simple wet chemical process.

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 ...

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.

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 …

We present here the seed-mediated growth of reduced graphene oxide-gold nanostar (rGO-NS) nanocomposites and employ them as active SERS materials for anticancer drug (doxorubicin, DOX) loading and release.

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.

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

在此，我们展示了一种基于还原氧化石墨烯/银纳米粒子（rGO/Ag NPs）复合材料的 SERS 活性基底，该复合材料通过简便的湿化学途径合成。 Ag NPs 修饰的 rGO 纳米片是通过在聚乙烯吡咯烷酮 (PVP) 和 NaCl 存在下在层状氧化石墨烯上用乙二醇还原 AgNO3 来实现的。

2025年3月1日 · We have synthesized a metal-free SERS substrate as the derivatives of Graphene oxide (GO) through wet chemical synthesis to detect an important industrial dye, Rhodamine B (RhB) used for benchmarking. The substrate has detected RhB in the micro-molar (µM) range with 3 orders of enhancement factor.

2018年10月17日 · Graphene oxide (GO) was synthesized by a modified Hummer’s method and was then reduced by the hydrothermal process. Both GO and reduced GO (rGO) were employed as surface-enhanced Raman scattering (SERS) substrates to detect rhodamine 6G (R6G).
