Surface‐enhanced Raman sensors: early history and the development of sensors for quantitative biowarfare agent and glucose detection
TL;DR: In this paper, the SERS enhancement factor, EFSERS, is optimized when the energy of localized surface plasmon resonance (LSPR) lies between energy of the excitation wavelength and the vibrational band of interest.

SERS of molecules that do not adsorb on Ag surfaces: a metal–organic framework-based functionalization strategy

TL;DR: Concentration dependence and time resolved measurements provide evidence for the hypothesis that the vapors are reversibly adsorbed on the surfaces of MOF nanocrystals exposed at grain boundaries, which represents a generalized approach for confining aromatic molecules through interactions with the MOF surface, which can be applied for future SERS-based sensors.

Probing Single Molecules and Single Nanoparticles by Surface-Enhanced Raman Scattering
Shuming Nie,Steven R. Emory +1 more
TL;DR: In this article, surface-enhanced Raman scattering was used to detect single molecules and single nanoparticles at room temperature with the use of surface enhanced Raman, and the intrinsic Raman enhancement factors were on the order of 10 14 to 10 15, much larger than the ensemble-averaged values derived from conventional measurements.
