Catching up with legal highs

10 Feb 2016

Graphical Abstract A team of British and Australian scientists has combined two spectroscopy techniques to rapidly identify new psychoactive substances from police drug seizures.

Designers of new psychoactive drugs, or ‘legal highs’, constantly tweak their chemical structure to avoid drug laws. And a lack of certified reference standards alongside the sample preparation required for established methods such as GC–MS and HPLC–MS has hindered high-throughput screening. So how do you test for drugs when you don’t know what you’re looking for? This is a problem currently facing forensic scientists.

How to tell your left from your right amino acids

26 Jan 2016

Graphical Abstract

Most amino acids exist in two forms that are chemically identical but are mirror images of each other, like left and right hands. Left-handed amino acids play a key role in biological processes and are vital to life. It therefore makes sense to want to differentiate between left and right-handed versions.

Uncoiling collagen using advanced computers

17 Nov 2015

British and French researchers have used modern computing power to enhance mass spectrometry and analyse an extremely complex collagen molecule in a short time scale.

Two-dimensional Fourier transform ion cyclotron resonance mass spectrometry (2D FT-ICR MS), developed in the 1980s, links the mass-to-charge ratios of precursors and fragments in complex samples. Compared to tandem mass spectrometry, 2D FT-ICR MS does not require isolated precursors and shows better resolution. Its applications have been limited, however, due to a lack of sophisticated computers.

Antibiotics pit against bacterial biofilms

28 Sep 2015

Graphical Abstract Scientists in the US have designed a simple and inexpensive electrochemical device that monitors bacteria metabolites to gauge the effect of antibiotics.

Monitoring bacterial growth is important for rapidly treating infections with the lowest effective concentration of antibiotics. The effectiveness of antibiotics is traditionally tested by adding patient samples to antibiotic mixtures then visually inspecting the antibiotic growth. However, this method requires large amounts of reagents and does not consider the effect of antibiotics on the bacterial biofilm.

Paper device tracks fracking pollution

07 Sep 2015

Scientists in the US have developed a simple paper-based sensor for detecting bromide ions in water. The device could be used to check if fracking fluids have seeped into water supplies.

Fracking involves forcing large amounts of fracking fluid – a mix of water, sand, biocides and other chemicals – into shale fractures at high pressure to extract shale gas. The resulting wastewater contains high concentrations of toxic chemicals including bromide, chloride and iodide ions and organic pollutants, and some wells can use around 17,000 cubic metres of water. Municipal treatment plants cannot cope with this volume of waste, and toxic halogenated byproducts can be created by the disinfection process.

Gordon F. Kirkbright Bursary Award, 2016, now open for nominations

The Gordon F. Kirkbright bursary award is a prestigious annual award that enables a promising student/non-tenured young scientist of any nation to attend a recognised scientific meeting or visit a place of learning.
The fund for this bursary was established in 1985 as a memorial to Professor Gordon Kirkbright in recognition of his contributions to analytical spectroscopy and to science in general. Although the fund is administered by the Association of British Spectroscopists (ABS) Trust, the award is not restricted to spectroscopists.

Applications are invited for the 2016 Gordon Kirkbright Bursary.

For further information contact John Chalmers at, email: vibspecconsult@aol.com

The closing date for entries is 31 December 2015.
