Journal Highlight: High-resolution Raman spectroscopy for the nanostructural characterization of explosive nanodiamond precursors

Date: Feb 6, 2017

Author: spectroscopyNOW

Raman and tip-enhanced Raman spectroscopy have been used to resolve morphological and structural differences of differently prepared hexolite nanocomposites used to prepare nanodiamonds by detonation.

Raman sex test: Saliva samples

Date: Feb 1, 2017

Author: David Bradley

A portable Raman scanner can analyse saliva, other bodily fluids, and reveal whether or not they come from a male or a female. The system developed by researchers at Albany University, SUNY, State University of New York, USA, may soon be available to scientific support for law enforcement.

Ising on the 2D cake: Raman in transition

Date: Jan 6, 2017

Author: David Bradley

Scientists in South Korea have used Raman spectroscopy to obtain the first experimental proof of a physics theory proposed more than 70 years ago.

Journal Highlight: Early diagnosis of influenza virus A using surface-enhanced Raman scattering-based lateral flow assay

Date: Jan 1, 2017

Author: spectroscopyNOW

A SERS-based lateral flow assay (LFA) kit with SERS-active nanotags for the rapid diagnosis of influenza virus A has a limit of detection one order of magnitude better than a colorimetric LFA kit.

Precision Raman: Effect in the field

Date: Dec 1, 2016

Author: David Bradley

New technology that could change the way in which electronics are printed facilitates high quality, direct spray deposition of semiconducting molecular crystals on to any surface. The precise nature of a single crystal field-effect transistor made this was has been ascertained using polarised Raman spectroscopy.

Journal Highlight: Allergic reactions in red tattoos: Raman spectroscopy for 'fingerprint' detection of chemical risk spectra in tattooed skin and culprit tattoo inks

Date: Nov 28, 2016

Author: spectroscopyNOW

Raman spectroscopy has been tested as a screening technique for chemical characterisation of tattoo pigments in pathologic reacting tattoos and tattoo ink stock products to depict unsafe pigments and metabolites.

Cocaine detection: Concentrating on SERS

Date: Nov 1, 2016

Author: David Bradley

A cocaine detector based on surface enhanced Raman spectroscopy (SERS) could be much more efficient and effective alternative to existing technology, according to researchers from Valencia and the Basque Country. Their approach works at very low concentrations of cocaine.

Journal Highlight: Inverse SORS for detecting a low Raman-active turbid sample placed inside a highly Raman-active diffusely scattering matrix – A feasibility study

Date: Oct 3, 2016

Author: spectroscopyNOW

A feasibility study has used inverse SORS to detect a very low Raman-active turbid sample inside a highly Raman-active diffusely scattering matrix, exemplifed by embedding chicken muscle tissue into solid paraffin blocks.
