Analyst issue 6 now online

23 Feb 2012

Analyst issue 6 is now published online with three exciting articles featured on the covers!

The front cover of this issue highlights work by Jin Cheng and colleagues from Tsinghua University and the National Engineering Research Centre for Beijing Biochip Technology, China. The group developed an electrical cell-substrate impedance sensing system for assessing in vitro cytotoxicity of anticancer drugs in a human kidney cell model. This system allowed for continuous and automatic measurements with a better resolution for drugs with different toxicity profiles.

The early-stage company Cobalt Light Systems has received European approval for its revolutionary INSIGHT100 bottle scanner, which could enable aircraft passengers to have liquid items larger than 100ml in their carry-on luggage.

The scanner uses Spatially Offset Raman Spectroscopy (SORS), a technique developed by Analyst Editorial Board member, Prof. Pavel Matousek of the STFC Rutherford Appleton Laboratory.

Pavel says, “Since STFC made the breakthrough in discovering SORS a few years ago, we have worked closely with the team at Cobalt Light Systems to develop and refine this technology. It is particularly exciting to see how this particular scientific development could now go on to make a real difference to the safety and wellbeing of our society.”

Submit your abstract for ARF 2012 – deadline approaching!

10 Feb 2012

If you thought you’d missed your chance to submit an abstract for a talk at the Analytical Research Forum 2012, good news: the deadline has been extended to Friday 17 February.

So make the most of this opportunity and submit your abstract today.

The annual Analytical Research Forum (ARF) is the premier Analytical Science meeting of the RSC. The meeting gives early-stage analytical science researchers (industrial scientists, Ph.D. students and postdoctoral fellows) the chance to present their latest results in the context of the wider analytical science community, and there will be prizes for the best contributions.

The programme will feature both poster sessions and lectures, including oral presentations from students, medal winners and international leaders in the field.

This year’s ARF takes place at Durham University, and will be Chaired by Dr Ritu Kataky.

We look forward to seeing you there!

Why not take a look at the latest issue of Analyst?

Featured on the front cover is a paper on the use of ambient ozone for the assignment of double bond position in unsaturated lipids. Stephen Blanksby and colleagues from the University of Wollongong, Australia, have made use of the fact that unsaturated lipids react with the low concentrations of ozone present in normal laboratory air.

Unsaturated lipids are deposited onto thin layer chromatography plactes and allowed to undergo ozonolysis. The products are then analysed by desorption electrospray ionization mass spectrometry (DESI-MS), providing unambiguous assignment of double bond positions without the need for instrument modifications.

Sun et al., Analyst, 2012, 137, 1125-1129

The back cover highlights research from Xiangying Sun and co-workers at Huaqiao University, Xiamen, China. They have developmed a novel dual-fluorescence quantum dot (QD) nanocomposite with tuning emission wavelength and fluorescence intensity which can selectively sense mercury ions (Hg²⁺) with a detection limit of 5.6 nM. They propose this can e used for the qualitative and semi-quantitative colorimetric analysis of Hg²⁺.
