Abstract :
In this paper, we introduce a simple and high-throughput technique for developing a strong surface-enhanced-Raman-Scattering (SERS) sensor by sandwiching dual gold nanoparticle (GNPs) on single layer graphene (SLG) for biomolecule detection. Through this way, the overall nanostructure size can be much closer to 10 nm which is more suitable for individual biomolecule sensing.
