A technique to combine the ultra-sensitivity of surface enhanced Raman scattering (SERS) with a slippery surface invented by researchers at Pennsylvania State University, University Park, PA, USA, will make it feasible to detect single molecules of a number of chemical and biological species from gaseous, liquid or solid samples.
Medical testing has been undergoing a quiet but extensive metamorphosis as labs adopt the versatile technology mass spectrometry, which enables more precise diagnosis. A special issue of Clinical Chemistry, titled “Clinical Mass Spectrometry: Achieving Prominence in Laboratory Medicine”, showcases recent medical advances that this technology has made possible.
Electro-optic modulators, which can switch light on and off within just picoseconds, are enabling ever faster telecommunication over fibre optics, and the same tools have now been harnessed for high-speed and accurate molecular sensing in the near infrared.
A new mass spectrometry test for detecting biomarkers for cancer and diabetes is more than 1000× more detailed and 100% faster than existing methods, new research by the University of Warwick, UK, suggests.
An international group of scientists from Poland, Austria and the UK have used X-ray fluorescence (XRF) spectroscopy at the UK’s Diamond Light Source to advance our understanding of the changes taking place during the progression of brain cancer. This research may lead the way to a new tumour assessment method which could complement traditional approaches.
A newly devised frequency comb provides a powerful light source, spanning frequencies of over 550 GHz with a total power of 5 mW. At the heart of the frequency combs are terahertz (THz) quantum cascade lasers (QCLs), which have the advantage of having both high power (in the form of THz radiation) and broadband capabilities (since the QCLs have gain over a wider frequency range). Combining these two elements to make a compact frequency comb generating long-wavelength light in the THz range can produce a useful source of radiation for a variety of applications in imaging, diagnostics, remote sensing and spectroscopy of extremely complex molecules.
Innovative new research led by the University of Exeter has demonstrated how the extraordinary properties of graphene can be exploited to create artificial structures that can be used to control and manipulate electromagnetic radiation over a wide range of wavelengths.
The 2015 Eastern Analytical Symposium Award for Outstanding Achievements in Near Infrared Spectroscopy has been presented to Benoît Igne.
Raman, FT-IR and ED XRF discover interesting detail of the dying in the 19th century, and maybe about trade links between Europe and Australia.
