Four-dimensional material maps: GAMERS method

Date: May 10, 2017

Author: David Bradley

Subtle effects governing the chemical, physical and optical properties of systems can be extracted using the multidimensional coherent Raman spectroscopic method called "GAMERS".

Journal Highlight: Resonance Raman and UV-visible microscopy reveals that conditioning red blood cells with repeated doses of sodium dithionite increases haemoglobin oxygen uptake

Date: May 1, 2017

Author: spectroscopyNOW

Raman confocal microscopy and UV–vis microscopy showed that successive additions of sodium dithionite to suspensions of red blood cells increased the rate and the capacity to uptake oxygen.

Journal Highlight: Resonance Raman of oxygen dangling bonds in amorphous silicon dioxide

Date: Mar 6, 2017

Author: spectroscopyNOW

A resonance Raman band induced by ionizing radiation in amorphous silicon dioxide, which can be detected under ultraviolet laser excitation, has been assigned to oxygen dangling bonds.

Influenza attack: Raman to reveal hijack

Date: Mar 1, 2017

Author: David Bradley

Laura Fabris of Rutgers University, New York state, USA, and her colleagues are using surface enhanced Raman scattering (SERS) spectroscopy to investigate the role that might be played by TIPs - therapeutic interfering particles in defending us against influenza, flu.

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.
