Abstract :
In this paper, we develop a strong surface-enhanced-Raman-Scattering (SERS) sensor by sandwiching dual gold nanoparticle (GNPs) on single layer graphene (SLG) for biomolecule detection. It´s a simple and high-throughput technique for producing GNPs sandwiched on SLG nano structures. The overall nanostructure size can be smaller than 10 nm which is more suitable for individual biomolecule sensing.
