Single molecule detection in gas-, solid- or liquid phases possible with slippery SERS

SLIPSERS-sA 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.

Frequency-agile laser frequency combs enable real-time NIR spectroscopy

NIR-Frequency-agile-comb-sElectro-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.

Synchrotron XRF could lead to better prognosis for brain cancer patients

Diamond_XRF_Brain_Cancer_Distribution-sAn 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.

Toward powerful and compact terahertz spectrometers

THz_frequency_combs-sA 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.
