Capped Ag nanoparticles with the novel silver core-molecule-silver cap structure were synthesized and demonstrated to produce strong SERS. Plasmon-induced electronic coupling was concluded to be the major Raman enhancement mechanism. The capped nanoparticles also exhibited polarization-dependent elastic light scattering that was attributed to the particle anisotropy, which resulted from the addition of the silver cap. These particles can potentially be used as optical labels.
