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.

On the inside front cover Christopher Szakal and colleagues at NIST, USA who present a novel method for correlating and classifying ion-specific time-of-flight secondary ion mass spectrometry (ToF-SIMS) images within a multispectral dataset by grouping images with similar pixel intensity distributions.

GRC on Bioanalytical Sensors

I’m writing this from Boston Logan Airport, waiting to catch my flight after the 2012 GRC on Bioanalytical Sensors, which took place at Salve Regina University, Newport, Rhode Island, USA. The nature of GRC meetings mean that a lot of unpublished data are presented, so I can’t go into detail but I can tell you that it was an interesting and stimulating few days of excellent science. And the weather was an improvement on Cambridge too!

Chair of the meeting was our Associate Editor Professor Steve Soper, and one of the Vice-Chairs was Professor Sue Lunte, Associate Editor for our sister journal, Analytical Methods. In addition, a number of speakers have published with us, not just in Analyst but in a variety of journals – this really reflects the diverse nature of the programme, from surface chemistry to biology.

We’ve collected together some of these papers, which will be free to access until 13 July – do the use the opportunity to (re)discover the best in this area of research.

Take a look at the collection of papers here.

Including:

Sampling techniques for single-cell electrophoresis
Christine Cecala and Jonathan V. Sweedler
Analyst, 2012,137, 2922-2929

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.

HOT article: highly sensitive copper sensor using nanoparticles and DLS

Copper(II) sensor based on gold nanoparticles and dynamic light scattering

Miao et al., Analyst, 2012, Advance Article

This HOT article features work from Xintao Shuai and colleagues of Sun Yat-Sen University, Guangzhao, China.

They present a novel, sensitive Cu2+ sensor based on the use of dynamic light scattering (DLS) to detect difference in the hydrodynamic diameter of gold nanoparticles (AuNPs). The ability of DNA to adsorb on the AuNPs changes with the presence of Cu2+, affecting the disperse state of the AuNPs and, therefore, their average hydrodynamic diameter.

The Cu2+ ion plays a key role in many metabolic processes, so being able to accurately determine levels of Cu2+ is important in various aspects of biology.

The authors applied their technique to water samples and say that it is both simple and timesaving, with the potential to be extended to other bioassays in the future.

Analyst, 2012, Advance Article
DOI: 10.1039/C2AN35217F

This paper will be free to access until 21 June 2012.

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.
