Journal Highlight: Raman spectroscopy analysis and mapping the biodistribution of inhaled carbon nanotubes in the lungs and blood of mice

Date: Nov 4, 2013

Author: spectroscopyNOW

The distribution and lung exposure of single-walled carbon nanotubes in CD-1 mice after exposure by inhalation have been studied by Raman spectroscopy.

Colon cancer: Spectral diagnostic

Date: Nov 1, 2013

Author: David Bradley

Researchers in Germany have developed a new use for Raman spectroscopy to support pathologists in the diagnosis of cancer. Writing in two parallel papers in the Journal of Biophotonics and the Analyst they compared conventional procedures for detecting colon cancer with their label-free spectroscopic histopathology method.

Journal Highlight: Raman and surface enhanced Raman scattering of a black dyed silk

Date: Oct 15, 2013

Author: spectroscopyNOW

The Raman and SERS spectra of a black dyed silk were measured based on isolated samples of Bombyx mori silk fibroin, its motif peptide component (GAGAGS) and the synthetic reactive black 5 dye.

Smarter drugs: Raman IV

Date: Oct 1, 2013

Author: David Bradley

Surface-enhanced Raman scattering (SERS) is about to make computerized smart systems that deliver drugs to hospital patients intravenously that much safer. Smart IV systems can deliver precise volumes at a precise rate, but they lack a critical ingredient to ensuring that the patient is not inadvertently harmed: they cannot know what concentration of drug has been added to the system nor can then confirm that it is even the correct drug being delivered.

Lip sync: Raman raises brand awareness

Date: Sep 1, 2013

Author: David Bradley

Forensic scientists in the UK have demonstrated that Raman spectroscopy can be used to identify the specific brand of lipstick someone was wearing at a crime scene without removing the evidence from its bag and so avoid possible cross-contamination and ensuring a secure prosecution.

Journal Highlight: The thermal stability of graphene in air investigated by Raman spectroscopy

Date: Aug 5, 2013

Author: spectroscopyNOW

The thermal stability in air of graphene synthesized by either chemical vapor deposition or mechanical cleavage is studied, which will be useful for guiding future electronics process and chemical decoration of graphene.

Nanotech enhancement: Gold rush

Date: Aug 1, 2013

Author: David Bradley

It is possible to tune gold nanoparticles with peptides for surface-enhanced Raman spectroscopy (SERS) in such a way as to side step the problematic stages inherent to other approaches to nanoplasmonic structures for analyte detection, according to Italian researchers.

Journal Highlight: Nanoscale chemical imaging using tip-enhanced Raman spectroscopy: A critical review

Date: Jul 2, 2013

Author: spectroscopyNOW

This review focuses on the prerequisites for the efficient coupling of light to the tip as well as the shortcomings and pitfalls that have to be considered for tip-enhanced Raman spectroscopy imaging, for its application to nanoscale analysis.
