Analyst 2011, 136(10): 1997-2184

Issue 10 of Analyst 2011 is now online.

Work by Alberto Escarpa and co-workers is highlighted on the front cover.  They have used a lab on a chip device to quickly analyse levels of zearalenone, a contaminant, in infant foods with a detection limit below legislative requirements.

This paper was recently highlighted by Chemistry World in a news piece.  The full article will be free to access until the end of May, so do take a look:

Integrated electrokinetic magnetic bead-based electrochemical immunoassay on microfluidic chips for reliable control of permitted levels of zearalenone in infant foods
Mirian Hervás, Miguel A. López and Alberto Escarpa

Issue 9 is now online! (apologies for the poetry, it’s just the best way to say it…)

Highlighted on this issue’s cover is work by Tony Killard and colleagues on the development of a fluorescent method for detecting the onset of coagulation in human plasma on microstructured lateral flow platforms.  They’ve found that the change in the distribution of the fluorescence within the sample over time was an excellent predictor of the onset of coagulation, which could be used to determine the clotting time.
