使用银纳米线上的传播等离子体激元作为激发源，我们在远离激光照射点的纳米颗粒/线连接处进行表面增强拉曼散射（SERS），灵敏度在几个分子范围内。还可以实现同时多站点远程激励 SERS 传感。
Using propagating plasmons on silver nanowires as an excitation source we perform surface-enhanced Raman scattering (SERS) at a nanoparticle/wire junction located remotely from the laser illumination spot with sensitivities in a few molecules range. Simultaneous multisite remoteexcitation SERS sensing can also be achieved.
