Surface-enhanced Raman spectroscopy (SERS) is a highly sensitive analytical technique that recently garnered attention due to its label-free detection capabilities. Traditionally, gold and silver nanoparticles have been employed in SERS substrates; however, using these metals presents issues such as biocompatibility and degradation. Therefore, this study aims to enhance the performance of graphene-mediated SERS (G-SERS) substrates for trace analysis. The research investigates the sensitivity of SERS regarding substrate dependence, graphene structure, and annealing effects.
