Single molecule surface-enhanced Raman Spectroscopy (SM-SERS) has the potential to revolutionize quantitative analysis at ultra-low concentrations (less than 1 nM). However, there are no established protocols to generalize the application of this technique in analytical chemistry. Here, a protocol for quantification at ultra-low concentrations using SM-SERS is proposed. The approach aims to take advantage of the stochastic nature of the single-molecule regime to achieved lower limits of detection (LOD) and quantification (LOQ)...
