Chemical Synthesis and Application of Silver Decorated Reduced Graphene as an Economically Viable Surface Enhanced Raman Scattering Based Substrate for Detection of Analytes in Trace Quantities

Abstract

In this work, we present a simple, economically viable technique of chemically synthesizing silver-decorated reduced graphene (Ag-rG) and its application in SERS analyte detection. We detected R6G (20 µL) up to 10–6 M using Ag-rG as a SERS-active substrate. R6G, a dye, is irradiated by a laser source (λ =785nm) and Raman spectra are acquired using integrated Raman setup (Renishaw). Ag-rG can be used for in-situ explosive detection, food/water adulterant detection, bio-diagnostics, narco-analysis, etc.
