Analyst Issue 16 now online

In this issue of Analyst we have two lovely covers for you to admire. On the outside we have an image from Sangmin Jeon and colleagues from Pohang University of Science and Technology, Korea. In their paper they report a new way of detecting Salmonella bacteria, a common cause of food poisoning. This simple, rapid, and cost-effective method used magnetic (superparamagnetic) nanoparticles and TiO2 nanocrystals.

From Zhong-Ping Yao at The Hong Kong Polytechnic University, China, comes the inside front cover. Together with a team from around China, they have been analyzing biological tissue at the molecular level. They have been able to directly ionize and analyze both plant and animal tissue by mass spectrometry under ambient conditions.

Issue 15 now online

Analyst, 2012, Issue 15 front cover

Front cover: Nagatani et al., Analyst, 2012, 137, 3422-3426

In the latest issue of Analyst, the front cover features work from Eiichi Tamiya of Osaka University, Japan, and co-workers. They have detected the influenza virus using an amplified DNA detection lateral flow immunoassay (ADLFIA).

The sensitivity of their method is comparable to agarose gel electrophoresis but can be observed by the naked eye. The authors say this work is a step forward in their efforts towards a battery powered portable PCR chip, and a battery powered portable PCR chip with ADLFIA has the potential to give the portable system a diagnostic test.

Analyst Issue 14 now online!

Park & Hong et al., Analyst, 2012, 137, 3249

Issue 14 for Analyst has now gone online for you to have a look at. We have some wonderful and interesting covers this time.

On the front cover we have an image from Tai Hyun Park, Seunghun Hong and colleagues from Seoul National University, Seoul, Korea. They have developed a biosensor that works on the same principles as the canine nose and have used it in the detection of hexanal, which is an indicator of the oxidation of food and food quality.

Gupta et al., Analyst, 2012, 137, 3216

Tarkeshwar Gupta from the University of Delhi and co-workers from India and Germany have given us our inside front cover this issue. In their communication they have made an efficient sensor for ascorbic acid using a copper complex-based monolayer on glass. They hope this is a step forward in research in monolayer-based remote-sensing devices and wireless sensor fabrication.

Professor Henry S. White, Guest Editor

Unlucky for some, but not for Analyst: Issue 13 is now online and features papers from the ‘Single’ issue, guest edited by Professor Henry S. White from the University of Utah. The issue features some great articles from authors such as Jonathan Cooper, Zuzanna Siwy, Lane Baker and Jonathan Sweedler.

In his Editorial, Professor White highlights the wealth of information that there is to be gained when analytical chemistry is studied at the “single entity” level.

Issue 12: online now

Analyst 2012, Issue 12, front cover

Potyrailo et al., Analyst, 2012, 137, 2777-2781

Take a look at the latest issue of Analyst.

Featured on the front cover is work from Radislav Potyrailo of GE Global Research, Niskayuna, New York, USA, and co-workers. They demonstrate roll-to-roll (R2R) fabrication of highly selective, battery-free radio frequency identification (RFID) sensors on a flexible polyethylene terephthalate (PET) polymeric substrate. Their RFID sensing concept features 16-bit resolution provided by the sensor reader, granting a highly desired independence from costly proprietary RFID memory chips with a low-resolution analog input. Future steps are being planned for field-testing of these sensors in numerous conditions.

DOI: 10.1039/C2AN16278D

On the inside front cover, Hans-Peter Loock and colleagues from Queen’s University, Kingston, Canada, look at online monitoring of the contamination of fuel with lubricants. They demonstrate that fiber-based Cavity-Ring-Down (CRD) absorption spectroscopy, and fluorescence Excitation–Emission Matrix (EEM) spectroscopy can provide the information that is needed to detect and quantify contamination and degradation products in machinery fluids.

Front cover: Schwab et al, Analyst, 2012, 137, 2541-2544

The latest issue of Analyst is now online, and we’re all about urgency as two exciting Communications feature on the covers.

On the front cover is work from Marcos Eberlin of the University of Campinas, São Paulo, Brazil and his colleagues.  They describe a simplified, fully portable version of Venturi easy ambient sonic-spray ionization (V-EASI) that now eliminates the need of laboratory gas cylinders and regulators.  This source, they say, seems to be one of the easiest to assemble and use, most economical yet effective and versatile platforms for ambient desorption/ionization mass spectrometry analysis of both solid and liquid samples.  Did you know that Marcos is an Associate Editor for our sister journal RSC Advances? Find out more here.

Analyst Issue 8 now online!

The latest issue of Analyst is now available online and we have three exciting covers for you to admire.

Analyst, Issue 8, 2012, Front CoverThe colourful front cover is from Hai Luo and colleagues from Peking University. They have studied the complexation reactions of insulin and other proteins with metal ions that are generated from the surface of substrates during laser irradiation as part of the process of laser desorption spray post-ionization mass spectrometry (LDSPI-MS).

By studying the type of sample plate material, laser and metal ions involved, they were able to make recommendations to optimise analysis to get the best possible results.

Analyst, 2012, 137, 1764-1767, DOI: 10.1039/C2AN16090K

Analyst, Issue 8, 2012, Inside front coverThe inside front cover from Hong Chen and Lin Yuan of Soochow University and co-workers has an informative image of a new sandwich ELISA method that has been developed for cancer detection.

Their work has found that an ELISA plate in sandwich format that is modified with a gold nanoparticle layer has an amplified signal and a lower limit of detection compared to other assays. This new assay was tested on a representative biomarker in human plasma and showed superior performance.
