Present and Future of Surface-Enhanced Raman Scattering

Judith Langer, +64 more
- 28 Jan 2020 - 
TL;DR: Prominent authors from all over the world joined efforts to summarize the current state-of-the-art in understanding and using SERS, as well as to propose what can be expected in the near future, in terms of research, applications, and technological development.
Journal ArticleDOI

SERS--a single-molecule and nanoscale tool for bioanalytics.

TL;DR: This critical review introduces the physics behind single-molecule SERS and discusses the capabilities of the effect in bioanalytics and surface enhanced hyper-Raman scattering (SEHRS).
Journal ArticleDOI

Surface-enhanced Raman scattering in local optical fields of silver and gold nanoaggregates-from single-molecule Raman spectroscopy to ultrasensitive probing in live cells.

TL;DR: This Account discusses surface-enhanced Raman scattering at extremely high enhancement levels that can occur for molecules attached to silver and gold nanoclusters, making gold and silver nanocluster very promising tools for studies of small structures in biological materials, such as cellular compartments.
Journal ArticleDOI

In vivo molecular probing of cellular compartments with gold nanoparticles and nanoaggregates.

TL;DR: The increase of the SERS signal strength and parallel TEM studies indicate the formation of nanoaggregates providing optimum SERS enhancement for ultrasensitive probing inside the endosomal compartment.
Journal ArticleDOI

Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) shows adaptation of grass pollen composition

TL;DR: The sensitivity of MALDI-TOF MS is demonstrated regarding the adaption of the chemical composition of three Poaceae (grass) pollen for different populations of parent plants by analyzing the mass spectra with partial least squares discriminant analysis (PLS-DA) and principal component analysis (PCA).
