Single molecule detector: IR graphene plasmonics

Date: Sep 1, 2016

Author: David Bradley

Graphene, the two-dimensional carbon allotrope could form the basis of a new plasmonic device capable of detecting single molecules of explosive materials, toxic chemicals, and other organic compounds using infrared, according to scientists at the Moscow Institute of Physics and Technology.

Journal Highlight: Prediction of methane emission from lactating dairy cows using milk fatty acids and mid-infrared spectroscopy

Date: Aug 1, 2016

Author: spectroscopyNOW

The suitability of mid-IR spectroscopy for predicting methane emission from lactating cows via their milk fatty acids is reviewed and the advantages and disadvantage are explored.

Drug testing: FTIR for festivals

Date: Aug 1, 2016

Author: David Bradley

A music festival is probably the last place you would expect to see a Fourier transform infrared spectrometer. But, under canvas a team of analytical chemists and drug advisers is hoping to help festivalgoers avoid the pitfalls of taking illegal drugs whose true constituents they know nothing about.

Say hello to SENIRA: Oil's well

Date: Jul 1, 2016

Author: David Bradley

Researchers in the US have, for the first time, demonstrated that surface-enhanced near-infrared absorption (SENIRA) spectroscopy can be used as a highly sensitive analytical tool.

Blue-light molecular motor: FTIR not seeing red

Date: Jun 1, 2016

Author: David Bradley

Shining blue light on a plate-like crystal suspended in water makes it continuously alternate between bending and stretching, acting as a light-controlled molecular motor.

Journal Highlight: Characterization of printing inks using DART-Q-TOF-MS and attenuated total reflectance (ATR) FTIR

Date: May 30, 2016

Author: spectroscopyNOW

ATR-FTIR spectroscopy and DART MS have been used in tandem to analyze four different classes of printing inks: inkjets, toners, offset, and intaglio.

Ulcerative colitis: Infrared diagnostics

Date: May 1, 2016

Author: David Bradley

Infrared technology could be key to minimally invasive screening for an often debilitating and worrying condition, ulcerative colitis. Moreover, the technology could offer a rapid, simpler and cost-effective diagnostic method that precludes the need for surgical biopsies and intrusive testing of the body, according to researchers at Georgia State University.

Journal Highlight: Characterizing prefrontal cortical activity during inhibition task in methamphetamine-associated psychosis versus schizophrenia: a multi-channel NIR study

Date: Apr 4, 2016

Author: spectroscopyNOW

Prefrontal cortical activity associated with a stop-signal inhibitory task was compared by NIR spectroscopy in patients with methamphetamine-associated psychosis and schizophrenia, and in healthy controls.
