Abstract
The bottom-up optimization of signal-to-noise ratios for SERS tags employing SAMSA fluorescein as the reporter was achieved using a bifunctional linker with low Raman cross section. By holding the nanoparticles at subnanometer separation, the linker allowed us to optimize the hot-spot thereby significantly reducing the fluorescence background. 2012
