TL;DR: A detailed study of the specific nanoparticle structures that give rise to single-molecule surface-enhanced Raman scattering (SMSERS) is presented and it is found that the electromagnetic SERS enhancement factors of 10(9) are easily obtained and are consistent with single- molecule SERS activity.

TL;DR: A detailed study of the wavelength and distance dependence of SERS is studied, which further illustrate predictions obtained from the electromagnetic enhancement mechanism, and an isotopic labeling technique applied to the rhodamine 6G (R6G)/silver system serves as an additional proof of the existence of single-molecule SERS and explores the dynamical features of this process.

TL;DR: This work describes the first Raman excitation spectroscopy studies of a single molecule, revealing new information previously obscured by the ensemble, and highlights the role of excitation energy in determining the resonance Raman intensities for R6G on surface-enhancing nanostructures.

TL;DR: A theoretical model of SERS detection indicates DLts below 1 ppb s(-1) for t(acq)= 1 s are, in fact, achievable using existing portable Raman instrumentation and AgFON surfaces, illuminating the importance of appropriate surface functionalization.

TL;DR: EELS mapping is demonstrated to be an invaluable technique for elucidating complex and overlapping plasmon modes in complex nanoscale architectures and correlate to optical data and classical electrodynamics calculations from the exact same particles.
