New Associate Editor for the Americas: Professor Evan Williams

Professor Evan WilliamsWe are delighted to announce the appointment of Professor Evan Williams of the University of California, Berkeley as our second Associate Editor for the Americas.

Professor Williams received his B.S. from the University of Virginia and his Ph.D. from Cornell University; he has held positions at Stanford University and Lawrence Berkeley National Laboratory, been a Visiting Professor at the University of Aarhus, Denmark, and received numerous awards.  His current group at Berkeley develops and applies novel instrumental and computational techniques in mass spectrometry, tandem mass spectrometry, separations, and laser spectroscopy to solve problems of fundamental interest in chemistry and biochemistry.

We’d like to welcome Evan and his expertise to the Analyst Editorial Board as Associate Editor alongside Professor Steve Soper – together, we look forward to further meeting the needs of our authors.

So, if you’re an author in the Americas, why not submit your paper?

Grand challenges in surface enhanced optical spectroscopies

Professor Duncan Graham

Take a look at Analyst Editorial Board member Duncan Graham’s contribution to our ongoing theme on Grand Challenges, which is included as part of Issue 19.

There remain several challenges to overcome in order to achieve widespread clinical use of surface enhanced techniques. In this review, Iain Larmour and Duncan Graham consider the substrates employed to achieve enhancement before reviewing each enhanced optical technique in detail; surface plasmon resonance, localised surface plasmon resonance, surface enhanced fluorescence, surface enhanced infrared absorption spectroscopy and surface enhanced (resonance) Raman spectroscopy.

Critical Review: Surface enhanced optical spectroscopies for bioanalysis

Issue 19 online

Analyst, 2011, 136(19): 3817-4084

The latest issue of Analyst is now available online.

On the front cover is work from Xuefeng Yin of Zhejiang University and colleagues.  One of the major difficulties in microfluidic cell analysis for adherent cells is that the cells are prone to attaching to the channel surface.  Yin et al present a simple 3D hydrodynamic focusing microfluidic device integrated with continuous sampling, rapid dynamic lysis, capillary electrophoretic (CE) separation and detection of intracellular content, which aims to overcome this:

Three-dimensional (3D) hydrodynamic focusing for continuous sampling and analysis of adherent cells
Chunxiu Xu, Min Wang and Xuefeng Yin
Analyst, 2011, 136, 3877-3883
DOI: 10.1039/C1AN15019G

The inside front cover highlights research by Srinand Sreevatsan of the University of Minnesota and collaborators from the University of Guelph.  Short RNA and DNA sequences (aptamers) have properties that make them desirable as biosensors for bacterial contaminants in food.  This paper describes the selection and characterization of a single, dominant aptamer (SSRA1), against the B-chain of the toxin ricin.  The results indicate that SSRA1 could serve well as pre-analytical tool for processing of ricin from liquid foods to aid current diagnostics as well as a sensor for direct ricin detection:

A single DNA aptamer functions as a biosensor for ricin
Elise A. Lamont, Lili He, Keith Warriner, Theodore P. Labuza and Srinand Sreevatsan
Analyst, 2011, 136, 3884-3895
DOI: 10.1039/C1AN15352H

Both papers will be free to access for 6 weeks.
