(A) SERS spectra taken from 4-methyl benzenethiol (4-MBT) immobilized on a dimer of silver nanospheres (at two different polarizations) and on a single silver nanosphere. (B) Summary of the SERS EFs calculated for individual silver nanocubes, and their dimers in face-to-face, edge-to-face, or edge-to-edge configuration. The samples were functionalized with 4-MBT. Each arrow indicates the laser polarization with respect to the corresponding SEM image. The scale bars represent 100 nm. Copyright (2009) Wiley-VCH. Reprinted with permission.
