Paul Bohn awarded the Theophilus Redwood Award

We are delighted to congratulate Paul Bohn, Chair of the Analyst Editorial Board on being awarded the 2010 Theophilus Redwood Award. This award given to a leading analytical scientist who is also an outstanding communicator. Paul was chosen as the award winner for the breadth and impact of his contribution to analytical science in the areas of microfluidics and nanoscale chemical sensing.

Paul gave his award lecture at the University of Strathclyde last Wednesday (30th March) and those present can confirm not only the excellence of his science, but also his ability to communicate this to his audience. He was presented with his medal by the President Elect of the Analytical Division, Alan Handley.

For more information about Paul’s work on nanoscale chemical sensing, please visit his website at the University of Notre Dame, USA.

The Awards Symposium also included the winner of the Robert Boyle Prize for Analytical Science given to Gary Hieftje of Indiana University, and the Harrison Meldola Memorial Prize which was awarded to Nathan Lawrence from Schlumberger Cambridge Research (shown below).

Congratulations to all three winners!

Parameters affecting traveling-wave ion mobility separation

Exploring the influence of ion heating on the accuracy of collision cross-section measurements using a traveling-wave ion mobility device

Ion mobility-mass spectrometry measurements are regularly used in biological chemistry for many applications.  This hot paper from Brandon Ruotolo and colleagues provides useful descriptions of important experimental parameters that affect ion mobility resolution and overall performance, and links this to theory.  One referee commented that this will “be a very useful paper especially to students and researchers who will be using the new generation IM-MS instruments”.

Read the article for free until May 10th.  Why not leave a comment below to let us know if you found the paper useful.

Pain-free uterine disease detection

Hope for non-invasive endometriosis diagnosis

Endometriosis affects around 10% of young women resulting in a wide range of symptoms. Currently diagnosis can only be performed by laparoscopic surgery.

A potential non-invasive method to detect endometriosis by acquiring a spectral signature of the uterus has been developed by Francis Martin and colleagues from Lancaster University. They used infrared spectroscopy together with computational analysis to analyse the difference between uterine tissue affected by endometriosis and normal tissue in the uterus.

Simple, low-cost and sensitive gold nanoflower immunoassay

Scientists from Fuzhou University, China, report the proof-of-concept of an enzyme-free amperometric immunoassay that uses gold nanoflower-labeled detection antibodies in this communication.  The gold nanoflowers achieve signal amplification by causing catalytic reduction of p-nitrophenol and redox cycling of p-aminophenol to p-quinone imine.

Making baby food safer

Scientists from Spain 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.

Alberto Escarpa and his team from Alcala University, in Madrid, have made a microfluidic device that can detect zearalenone levels to well below the maximum legal amount.
