使用溶剂辅助纳米转印（S-nTP）技术实现等离子体纳米结构的3D堆叠，以提供用于高灵敏度表面增强拉曼光谱（Sers）分析的极其密集和规则的热点阵列。此外，通过在连续金属膜或石墨烯表面上印刷纳米线获得的混合等离子体纳米结构由于垂直等离子体耦合而显示出显著增强的Sers信号。
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.
