Surface-enhanced Raman scattering inside metal nanoshells.
We show the experimental observation of SERS inside metal nanoshells for the first time. Giant enhancement, solely due to the electromagnetic enhancement in the near field and on the order of 10(11) to 10(14), can be consistently and reproducibly achieved. The results provide new insights to the SERS effect and pave the way for a new design of nanostructures to be used as SERS-tags for Raman-based assays and imaging.
