Abstract

We introduce a technique, which results in 10X improvement in precision of surface enhanced Raman spectroscopy measurements, by combining dual Raman/Electrochemical measurements, at multiple sites with induced diversity. We carried out our experiments at fixed analyte concentrations while varying nanoparticle concentrations. Each concentration of nanoparticles gave rise to different Raman signal intensities, thus providing a three-point matrix to confirm the analyte concentration.
