A chip-based device can generate a laser signal with frequencies spaced in a comb-like fashion. In general, light and water waves alike stretch out and dissipate as they move further and further away from their source. However, there is a type of wave that maintains its shape as it propagates: solitons.

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.

A new test for detecting biomarkers for cancer and diabetes based on two-dimensional mass spectrometry is more than 1000× more detailed and 100% faster than existing methods, new research by the University of Warwick, UK, suggests.

In this platform, an aqueous or oil droplet containing gold nanoparticles and captured analytes is allowed to evaporate on a slippery substrate, leading to the formation of a highly compact nanoparticle aggregate for surface enhanced Raman scattering (SERS) detection.

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.

Photonis USA has announced that it has reached an agreement with MasCom Technologies GmbH of Bremen, Germany, to stock and resell a wide selection of discrete dynode electron multipliers designed for use in inductively coupled mass spectrometry (ICP-MS) instruments. The agreement adds to Photonis’ extensive line of electron multiplier products.

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.
