Abstract
AbstractIntegrating noble metal nanoparticles and graphene materials to enhance the Raman signal is of great significance in surface‐enhanced Raman scattering which enhancement silver nanoparticles (Ag) which are reported one of the strongest plasmonic properties materials that are easily synthesized. Graphene and its derivatives such as reduced graphene oxide (rGO) are capable of increasing the charge transfer between the adsorbent and the substrates leading to a chemical mechanism. The combination of the rGO/Ag nanohybrids shows great potential as substrates which is the association of the electromagnetic and chemical mechanism for more enhancement of the Raman signal. We report a rapid, easy, and low‐cost method to fabricate rGO/Ag substrate for SERS using methylene blue as a probe molecule. The density of Ag This material exhibits superior sensitivity for detecting methylene blue down to a concentration of 10−9 M and enhancement factor SERS calculated reaches 108 demonstrations of the excellent Raman signal enhancement of rGO/Ag substrate. The relative standard deviation value calculated is 4.91% showing extremely good homogeneity and reproducibility, indicating the potential application in quantitative determination. The obtained results contribute to the development and optimization of substrates for application in the detection of trace amounts of organic substances in food and environmental applications.
