Journal Highlight: Applicability of Fourier transform infrared (FTIR) spectroscopy in rapid identification of some Candida and dermatophyte species infections in humans

Date: Nov 1, 2016

Author: spectroscopyNOW

FTIR microspectroscopy has been used to obtain molecular fingerprints of Candida and dermatophyte species from 50 patients with superficial fungal infections in a single measurement.

Are metamaterials electric: Infrared imaging

Date: Nov 1, 2016

Author: David Bradley

A hybrid metamaterial behaves like an electric version of the chameleon's skin, changing colour when a current is applied but also becoming warmer, at least when viewed in the infrared. This could be the first proof-of-principle of a controllable metamaterial device, according to engineers at Penn State University.

Journal Highlight: Toward extreme biophysics: Deciphering the infrared response of biomolecular solutions at high pressures

Date: Sep 5, 2016

Author: spectroscopyNOW

FTIR spectroscopy and computer simulations have been used to reveal the molecular response of piezolytes in water under high pressure to gain insight into biomolecular function at pressures relevant to life on Earth under extreme conditions.

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.
