Another paper - this time Henry's excellent work with DSTL on using DEP to extract soil particles from airborne samples, following on his previous work on diesel particle extraction. The paper will be availabel when possible.

Many thanks to Nic Green for organising a great meeting at the Institute of Physics. Dielectrophoresis 2014 was a great success, with some titans of the field in attendance. A great time - and great science - from one and all.

Fatima, Sina, Erin, Kai and Mike were there - spot them below! (Marios also presented but isn't in the pic). Also there was Rula Abdallat, Surrey DEP alumnus,

Sina Mahabadi, PhD student in the group, has presented his wok at the American Association for Cancer Research (AACR) Annual Meeting in San Diego. Here he is at his poster, “Measurement of Gifinitib (ZD1839) effect on electrophysiological properties of head and Neck cancer cells using Dielectrophoresis (DEP)”.

Congratulations to Sabry Mohamad (not pictured), Tom Wells and Ruth Torcal Serrano, who all graduated with their PhDs today. Sabry's PhD was in dielectrophoresis of macromolecules, whilst Tom's and Ruth's were both in the field of 3D dielectrophoresis optimisation and applications.

Our most recently accepted paper is now available for download from the Integrative Biology website. Written with our colleagues at the Gade Institute in Norway, the work looks at how the degree of stem-ness in cancer cells can be tracked according to the membrane electrical properties, The paper shows how the changes in the mambrane correlate with changes in morphology that might allow cancer cells to metasticise more easily, and how DEP could be a potential fractionation tool in the future. We will make the paper available as soon as we can.

February saw the publication of two works in successive issues of the journal Electrophoresis, both on electrohydrodynamic particle focussing. The first, led y Nazim Mohtar, shows how the focussing of particles onto electrode pads for sensing can be optimised, but also proves fascinating insight into the mechanism of collection, which is heavily influenced by medium viscosity. The second paper, led by Kai, looks at the use of the technique in the presence of flow, to sheperd particles to one side of a channel. The technique looks capable of concentrating up to seven times in continuous outlet flow, with scope for extension by cascading. As usual, more details on the Journal Papers page.

Sabry Muhamad's paper on dielectrophoretic manipulation of DNA has now been published in IEEE Transactions on Nanobioscience, under its new editor Henry Hess. The paper shows how DEP can be used to show different conduction mechanisms in DNA made of AT-only and GC-only DNA. More information can be found on the Journal page.
