Analyst issue 4, 2012 – now online!

The latest issue of Analyst is now available online!

In this issue, the front cover features work by Aaron Timperman and colleagues from West Virginia University, USA, who report the fabrication and performance of a microfluidic traveling-wave electrophoresis system, a promising new separation technique.  It uses a locally defined traveling electric field wave within a microfluidic channel in order to achieve band transport and separation.  The authors anticipate that this technique will open up many future lab-on-a-chip applications, processes and systems.

The inside front cover of this issue highlights work by Hui-Fen Wu and Kamlesh Shrivas from the National Sun Yat-Sen University, Taiwan, who report the rapid and sensitive protein extraction by cobalt oxide nanoparticle-based liquid-liquid microextraction coupled with MALDI-MS.  The show for the first time that the metal oxide nanoparticles prepared in the organic phase can be successfully applied to the extraction and preconcentration of proteins, and their approach offers distinct advantages including high sensitivity for washing and separation-free MALDI-MS analysis of proteins.

Analyst Issue 3, 2012: now online

Analyst 2012, Issue 3, front cover

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.

The inside front cover features a communication from Andreas Manz of KIST Europe, Germany and his collaborators.  They present a label free quantitative detection method for DNA samples amplified by polymerase chain reaction (PCR) in aqueous medium using terahertz-time domain spectroscopy (THz-TDS)

Our back cover highlights research from Sangmin Jeon of Pohang University of Science and Technology (POSTECH), Korea, and his co-workers.  They adopted a dynamic light scattering (DLS) method to measure the corrosion of iron nanoparticles.  The nanoparticle corrosion rate determined by DLS was found to be almost identical to the value obtained by conventional immersion tests.

Issue 2 now online

Analyst, 2012, Issue 2 front coverThe 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.

(*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!)

First issue of 2012 now online!

Analyst 2012, Issue 1 covers

Analyst, 2012, 137(1): 1-276

An early New Year present from Analyst: it’s Issue 1 of 2012, which has now been published online.

We start the year as we mean to go on, with some excellent cover articles with equally good cover images.

On the front cover is an article from Jason Greenwood and colleagues from Queen’s University, Belfast on mass spectra obtained from the interaction of intense, femtosecond laser pulses with 1,3-butadiene, 1-butene, and n-butane.  They discuss potential mass spectrometry applications of the technique, such as the analysis of catalytic reaction products.
