Andor Technology’s electron multiplying CCD camera is being used in combination with an imaging spectrograph and a sheath flow cuvette by researchers at the La Jolla Bioengineering Institute in California, USA. They have been able to analyse individual nanoparticles at rates of 100 per second or faster. This will remove current bottlenecks with characterising single nanoparticles, potentially leading to the development of brighter and more uniform tags for use in biomolecular detection and cancer therapeutics. www.andor.com/scientific_cameras/newton/
Professor Bonnie Ann Wallace of Birkbeck College, University of London, UK, has received the 2009 Royal Society of Chemistry Interdisciplinary Prize and the 2010 AstraZeneca Award from the Biochemical Society for her work on Development of Methods and Applications for Circular Dichroism and Synchrotron Radiation Circular Dichroism Spectroscopy. She has also recently co-edited (with Dr Robert William Janes of Queen Mary, University of London) a book published by IOS Press on Modern Techniques for Circular Dichroism and Synchrotron Radiation Circular Dichroism Spectroscopy.
The DASp, German Working group for Applied Spectroscopy, regularly awards the “Bunsen-Kirchhoff-Preis für analytische Spektroskopie” to honour preferably the work of young scientists from universities, research institutes or industry who made excellent contributions to analytical spectroscopy. Especially preferred is an oeuvre in new areas like spectroscopy in nano compartments, spectroscopy of biomolecules etc. The Award consists of an award-document and an amount of €2500 sponsored by PerkinElmer GmbH and the DASp seeks nominations for the 2010 Bunsen–Kirchhoff Award for Analytical Spectroscopy. The Award will be presented at Analytica in March 2010 in Munich, Germany.
A nomination should include: 1) letter with the candidate’s accomplishments; 2) list of publications or recent work; 3) scientific curriculum vitae stating the age of the candidate; the candidate’s address, phone fax and e-mail.
Nominations can be made by members of DASp but eligibility is open for any scientist meeting the requirements. Self-nomination is not allowed.
Since a failed terrorist attack in 2006, plane passengers have not been able to carry bottles of liquid through security at airports, leaving some parched at the airport and others having expensive toiletries confiscated, but work by a group of physicists in Germany is paving the way to eliminate this necessary nuisance.
For high-precision spectroscopy and structural studies of molecules, short light flashes with lowest possible wavelength, i.e., high photon energy, are required. Currently, x-ray flashes of some attosecond (10–18 s) duration are accessible experimentally. Even shorter pulses with even higher photon energy would improve the temporal and spatial resolution, or would allow for the investigation of even smaller structures, such as for example atomic nuclei. In so-called pump-probe experiments, two light pulses of exactly controllable distance are utilised to observe rapid system changes in slow motion.
Scientists at Queen’s University Belfast are developing a Raman spectroscopy-based sensor to detect chemical agents and illegal drugs which will help in the fight against the threat of terrorist attacks. Special gel pads will be used to “swipe” an individual or crime scene to gather a sample which is then analysed by the Raman instrument that can detect the presence of chemicals within seconds. This will allow better, faster decisions to be made in response to terrorist threats.
