Abstract: 3D stacking of plasmonic nanostructures is achieved using a solvent-assisted nano-transfer printing (S-nTP) technique to provide extremely dense and regular hot spot arrays for highly sensitive surface-enhanced Raman spectroscopy (SERS) analysis. Moreover, hybrid plasmonic nanostructures obtained by printing the nanowires on a continuous metal film or graphene surface show significantly intensified SERS signals due to vertical plasmonic coupling.
