5th Workshop on Microfluidics

The 5th Workshop on Microfluidics was held on the National Center for Research on Energy and Materials (CNPEM) in Campinas, Sao Paulo (Brazil), from July 23-24, 2015. Since 2011, the workshop has brought together young students, researchers, and companies from different states of Brazil to discuss topics related to fundamentals, fabrication technologies, innovations, and applications in microfluidic science. This field has been spread out around different regions of Brazil presenting outstanding contributions for microfabrication and microfluidic technologies.

The event was supported by the Royal Society of Chemistry (RSC) for the third time. Representing the scientific board of the V Workshop on Microfluidics, Prof. Charles Henry from Colorado State University, USA, presented the awards to the three best works which were awarded by the RSC .

Analyst Award was awarded to Eduardo L. Rossini, from Universidade Estadual Paulista, Araraquara (Brazil), for the work “Simultaneous determination of uric acid and creatinine using μPAD”. Furthermore, Roger Cardoso Moreira, from Universidade Federal de Goiás, Goiânia (Brazil), received the Analytical Methods Award for the work “Adaptation of a commercial electrophoresis system for quaternary amines separation in microchips”. Lastly, the Lab on a Chip Award was given to Houari Cobas Gomez, from Instituto de Pesquisas Tecnológicas, Sao Paulo (Brazil), for the work “3D focalization LTCC microfluidic device for nanoparticle synthesis by nanoprecipitation”.

On behalf of the organizing committee, I would like to thank the support received from the RSC.

Sincerely yours,

Angelo Luiz Gobbi

Microfabrication Laboratory – LNNano

SERS based magnetic immunoassay for cancer biomarker HE4

Schematic diagram of magnetic immunoassay based on SERS

Women with gynaecological malignancies are at high risk of developing ovarian cancer (OC). OC does not show any symptoms in the early stages, resulting in a delay in detection and definite diagnosis is obtained in the later stages. At present, ultrasonic imaging and assay of biomarkers (e.g. Human epididymis protein 4, HE4 ) are used for the diagnosis of OC. But the ultrasonic imaging can not discriminate between benign and malignant tumours and the immunoassays are time consuming, require sophisticated equipment and skilled professionals. Therefore, there is an urgent need for the development of a sensitive method for trace assay of biomarkers such as HE4. Jianlin Yao and colleagues from the Soochow University have developed a new approach based on surface enhanced Raman spectroscopy (SERS) and a magnetic immunoassay technique for rapid detection and separation of HE4 with high sensitivity and selectivity. ‘ The immuno nanoparticles studied could be developed as reagent kits in the clinical diagnosis of cancer’, opines Jianlin Yao. To learn more about the study, read the full article for free* by following the link given below.

Royal Society of Chemistry NMR Discussion Group – 8th Annual Postgraduate Meeting, University of Manchester

A conference report by Stephen Byard – NMR DG Secretary.

The annual NMR Discussion Group Postgraduate  Meeting  is  now  an established event and the 8th  meeting was hosted by the School of Chemistry, University of Manchester.  As always, the meeting provided an ideal forum for early career research workers to present their work in an informal environment, either orally or as a poster.    Established researchers, from both academia and industry, also attended the meeting as delegates.  A diverse range of topics was presented, covering all magnetic resonance related disciplines, including small molecule  characterisation,  solid-state NMR, imaging and molecular biology.

To complement presentations given by early career  research  workers,  overview  lectures  were  delivered  by  Professor  David Middleton (University of Lancaster) and Dr Mathias Nilsson (University of Manchester) on ‘Adventures in Biomolecular Design and Solid-State NMR’ and ‘Pure Shift NMR’ respectively.  The meeting was sponsored by Thermo Scientific and the Royal Society of Chemistry, and prizes were awarded for the best oral and poster presentations. Judging was carried out by three independent members of the NMR Discussion Group Committee.

Graphical Abstract
The prize for the best oral presentation was awarded to Davy Sinnaeve (Ghent University/University of Manchester), for his work on Ultrahigh resolution 1H – 1H coupling measurements, by Professor Gareth Morris  (NMR  DG Chairperson) and  Dr   Andrew   McLachlan  (Thermo Scientific).

Call for papers: themed collection dedicated to food authenticity and integrity

Cover image for Analytical Methods issue 2You are invited to contribute to the joint Analyst and Analytical Methods themed collection showcasing the latest discoveries and developments in food authenticity and integrity; including the analysis and detection of food fraud, contamination, adulteration and spoilage.

For your article to be considered for the themed collection we must receive your manuscript by 13 July 2015.

Guest Edited by Professor Roy Goodacre and Dr David Ellis at The University of Manchester, this upcoming collection will showcase the latest developments on food analysis by leading researchers from academia, industry and government departments.

As you are no doubt aware the recent horsemeat scandal throughout Europe rocked the food industry and this precipitated the recent Elliott review. History across the globe reminds that our food is under constant threat from adulteration and previous examples include: melamine in milk, dioxins in pork, and microbial pathogens. Adulteration, contamination and spoilage of food has therefore always been an international problem and there is a constant requirement for analytical methods to be developed in order to assess the food we, our companion animals and veterinary animals consume.

Submissions are welcome to both Analyst and Analytical Methods for the themed collection which will include research and reviews across the fundamental and applied analytical sciences.

Please don’t hesitate to contact us if you are interested in submitting a Communication, full paper or review article for the collection, or if you would like more information about the journals or themed collection
