Surface-Enhanced Raman Scattering (SERS) of Microorganisms

Israel Journal of Chemistry, 2006
AbstractNormal Raman (NR) spectra and surface‐enhanced Raman scattering (SERS) spectra were obtained for the bacterium Escherichia coli and were compared with those of two other microorganisms, Haloferax volcanii and Thiobacillus neapolitanus. It was found that at 514 nm the SERS of E. coli was similar to that of flavin adenine dinucleotide (FAD). Upon

Surface-Enhanced Raman Scattering (SERS), Applications

2017
Surface enhanced Raman scattering (SERS) is a sensitive and selective spectroscopic technique for the detection and characterization of analytes, which are adsorbed on suitable metal surfaces. The effect was first discovered experimentally in 1974 by Fleischmann et al., who reported very intense Raman bands from pyridine adsorbed onto an ...

Polarization-dependent effects in surface-enhanced Raman scattering (SERS)

Physical Chemistry Chemical Physics, 2006
A few key examples of polarization effects in surface-enhanced Raman scattering (SERS) are highlighted and discussed. It is argued that the polarization of the local field, which is felt by an analyte molecule in a location of high electromagnetic field enhancement (hot-spot), can be very different from that of the incident exciting beam.

Surface-enhanced Raman scattering (SERS) at Copper(I) oxide

Journal of Raman Spectroscopy, 1998
<p>Surface-enhanced Raman scattering spectra of pyridine at a copper(I) oxide hydrosol and at Cu<sub>2</sub>O-covered copper electrode produced by 'oscillating reaction roughening' are reported. It is shown that on such surfaces pyridine molecules adsorb as pyridinium cations.

On the importance of optical forces in surface-enhanced Raman scattering (SERS)

Faraday Discuss., 2006
This contribution reports on the combination of optical tweezers with SERS spectroscopy of colloidal silver nanoparticles covered by thiophenol. The experimental design is based on two different laser beams, one used for Raman excitation (lamda = 514.5 nm) and one for optical tweezing (lamda=830 nm).

Raman and surface-enhanced Raman scattering (SERS) biosensing

SPIE Proceedings, 2013
Raman scattering (RS) is a widely used vibrational technique providing highly specific molecular spectral patterns. A severe limitation for the application of this spectroscopic technique lies in the low cross section of RS. Surface-enhanced Raman scattering (SERS) spectroscopy overcomes this problem by 6-11 order of magnitude enhancement compared with
