Journal Highlight: Glycan fingerprinting via cold-ion infrared spectroscopy

Date: Jul 3, 2017

Author: spectroscopyNOW

Cold-ion IR spectroscopy of oligosaccharide ions reveals many well-resolved absorption features that are diagnostic for minute structural variations, making it a key technology combined with mass spectrometry to unravel complex glycomes.

Combing the atmosphere: IR gas signatures

Date: Jul 1, 2017

Author: David Bradley

An infrared laser that can comb the air between it and a quadcopter flying perhaps several kilomnetres away can reveal precisely what gases are in the atmosphere over a city or other region, according to NIST scientists.

Answering Life's Questions with Spectroscopy

Date: Jun 28, 2017

Author: Jon Evans

Spectroscopy has been a common analytical technique in laboratories for many years. Recently, however, it has begun to emerge from the laboratory, both figuratively and literally, as more and more researchers discover that it is ideally placed to answer the questions they want to ask.

Journal Highlight: A novel library-independent approach based on high-throughput cultivation in Bioscreen and fingerprinting by FTIR spectroscopy for microbial source tracking in food industry

Date: Jun 6, 2017

Author: spectroscopyNOW

A new library-independent approach for microbial source tracking based on high-throughput liquid microcultivation and FTIR spectroscopy has high potential for routine control in the food industry due to low costs and analysis time.

Elusive effect: New IR detectors

Date: Jun 1, 2017

Author: David Bradley

The existence of a previously unobserved phenomenon related to particles known as Weyl fermions has been observed in Weyl semi-metals by an international high-energy physics team. The discovery could lead to a new type of infrared detector.

Journal Highlight: Quantitative IR microscopy and spectromics open the way to 3D digital pathology

Date: May 1, 2017

Author: spectroscopyNOW

The reconstruction of 3D quantitative chemical images of biological tissue by FTIR spectromicroscopy is reported, using an automated curve-fitting method to extract all of the intense absorption bands.

Emission control: Infrared metamaterial

Date: May 1, 2017

Author: David Bradley

A meta material that can be tuned to emit different wavelengths of infrared light in a controlled manner having absorbed energy could be used to make a device for collecting and so using waste heat.

Journal Highlight: The analysis of scalp irritation by coacervates produced in hair shampoo via FTIR with focal plane array detector, X-ray photoelectron microscopy and HaCaT cells

Date: Apr 3, 2017

Author: spectroscopyNOW

A coacervate that forms on the scalp from hair washing products has been characterised as a cationic polymer containing an anionic surfactant using FTIR-FPA and X-ray photoelectron microscopy.

Disease detector: Early signs visible to infrared

Date: Apr 1, 2017

Author: David Bradley

Fourier transform infrared (FTIR) spectroscopy can detect and characterize the release of sub-micrometre sized microvesicles and how they change in response during the body's immunological response to bacterial infection.
