Analyst (2012), 137(3): 529-788

Take a look at the latest issue of Analyst, which features three excellent cover articles.

Featured on the front cover is work from Martin Pumera and colleagues of Nanyang Technological University, Singapore. They studied the performances of several chemically modified graphene nanomaterials as sensing platforms by using the electrochemical impedance spectroscopy technique for the detection and believe that their findings may present a foundation for further research and development in graphene-based impedimetric biosensing.

HOT article: recognising different human telomeric G-quadruplex conformations

06 Jan 2012

By Vibhuti Patel, Deputy Editor.

Recognition of different human telomeric G-quadruplex structures is very important in anti-cancer drug design, but is challenging due to the presence of multiple conformational isomers.

Yalin Tang and fellow researchers from the Chinese Academy of Sciences have looked to tackle this problem. In their latest article, three different conformations have been recognised using quinacrine, via monitoring of absorption, fluorescence and fluorescence lifetime spectra.

The recognition mechanism is based on the different binding affinity and binding sites has been further elucidated by association with the nuclear magnetic resonance (NMR) results.

Issue 2 now online

15 Dec 2011

By Vibhuti Patel, Deputy Editor.

The second issue of 2012 is now online.

Featured on the front cover are Optical Chemical Sensors (Optodes), which have proven to be a versatile and powerful analytical tool often comparable or even better than traditional electrochemical sensors. In this study Aron Hakonen from the University of Gothenburg and Niklas Strömberg of the SP Technical Research Institute of Sweden show that a nanoparticle enhanced ammonium fluorosensor is suitable for non-invasive high-quality ammonium imaging of complex samples.

The plasmon sensitized optical sensors were utilized as a bioanalytical tool for chemical imaging of natural degradation processes occurring in biological tissues. Analytical performance of the nanoparticle enhanced sensors confirmed superior sensitivity, reversibility, durability and overall image quality over non-doped sensing membranes.

In addition, a straightforward square root function was utilized to improve image quality and simplify the calibration process.

They say that the nanoparticle interaction/coextraction based sensing scheme utilized in this study is general and can be used for numerous ions, preferably combined with the diffusion consistent calibrations for superior analytical performance.

On the back cover is work from Hui-Fen Wua and colleagues at the National Sun Yat-Sen University, Kaohsiung, Taiwan on the detection of bacteria using physical preconcentration coupled ZnO NPs assisted MALDI-MS (PP-MALDI-MS). Ants and humans coexist closely and for the most part happily, but this work shows that perhaps these insects aren’t as harmless* as they seem. Their study is an attempt to highlight the ability of these seemingly harmless ants to collect bacteria from their surroundings and transport them, and they confirmed that ants are potent carriers of bacteria and are good indicators of the bacteria present in the specific environment.

These articles will be free for 6 weeks so take a look and let your colleagues know.

(*as someone who has been bitten by a soldier ant in the jungle, I have to disagree with the assessment of these insects as harmless!)

06 Dec 2011

By Hannah Porter, Publishing Assistant.

The Trustees of the Analytical Chemistry Trust Fund announce the Analytical Chemistry Summer Studentship Scheme:

The purpose of the awards is to give experience of research to undergraduates with research potential and to encourage them to consider a career in Analytical Chemistry research on completion of their undergraduate degree.

The awards provide support for the student at a rate of £180 per week (£190 per week in London), for a period of between 6 and 8 weeks during the summer vacation.

Applications for funding should be made by the supervisor (Industrial or Academic) wishing to host a studentship in the field of Analytical Chemistry.

Visit the website for more details and to apply.

HOT article: Detecting water in fuel

02 Dec 2011

By Vibhuti Patel, Deputy Editor.

Take a look at this HOT paper from Editorial Board member Boris Mizaikoff.

Water is a common contaminant in industrial oils and petroleum products. It impairs the performance and longevity of machinery, so it’s important to detect it in these products. A previous approach has involved off-site analysis, but this method is time consuming and may be compromised because of the potential variability in water concentration introduced by storage, transportation or shipment of a sample.

Here, Professor Mizaikoff and colleagues have focused on quantifying trace amounts of water in hydrocarbons using hexane as a model system for industrial oils and petroleum using mid-infrared evanescent field absorption spectroscopy.

They used a silver halide fibre optic waveguide to interrogate in situ water-in-hexane emulsions. The limits of detection and limits of quantification of water in hexane using tin-crosslinked polyacrylic acid modified fibres were 76 and 170ppm, respectively. The IR absorption signature of water in hexane was detected at concentrations as low as 10ppm.

The strategy requires a single measurement, requires no sample preparation and has the potential for direct in situ detection.
