Journal ArticleDOI
Surface-Enhanced Raman Spectroscopy for Bioanalysis: Reliability and Challenges
TL;DR: An outlook of the key challenges in bioanalytical SERS, including reproducibility, sensitivity, and spatial and time resolution is given.
Journal ArticleDOI
Label-Free Surface-Enhanced Raman Spectroscopy Detection of DNA with Single-Base Sensitivity
TL;DR: Iodide-modified Ag nanoparticles are used to obtain highly reproducible SERS signals of single- and double-strand DNA in aqueous solutions close to physiological conditions and the phosphate backbone signal was used as an internal standard to calibrate the absolute signal of each base for more reliable determination of the DNA structure.
Journal ArticleDOI
Label-Free Detection of Native Proteins by Surface-Enhanced Raman Spectroscopy Using Iodide-Modified Nanoparticles
TL;DR: An iodide-modified Ag nanoparticles method (Ag IMNPs) for label-free detection of proteins and the qualitative identification of proteins by simply taking the intensity ratio of the Raman peaks of tryptophan to phenylalanine residues is demonstrated.
Journal ArticleDOI
Mechanism of Cellular Uptake of Graphene Oxide Studied by Surface-Enhanced Raman Spectroscopy
TL;DR: In this article, surface-enhanced Raman scattering (SERS) spectroscopy is employed to investigate the cellular internalization of GO loaded with Au nanoparticles (NPs) by Ca Ski cells.

TL;DR: The method is established based on the finding that the SERS background originates from the LSPR-modulated photoluminescence, which contains the local field information shared also by SERS, which validate this concept of retrieval of intrinsic fingerprint information in well controlled single metallic nanoantennas of varying aspect ratios.
