Three different delivery concepts (standard diffusion, global electrodynamic precipitation, and localized nanolens‐based precipitation) and three different SERS enhancement layers (a silver film, a nanolens‐based localized silver nanoparticle film, and the standard AgFON) are compared. The nanolens concept is applied to increase the SERS signal: a factor of 633, when compared to a standard mechanism of diffusion, is observed.
