ICP-MS was used to measure 46 different elements in 37 Azobé (Lophira alata) trees at two forest sites in Cameroon to determine the multi-elemental composition of trees in an effort to combat the illegal trade of timber.

Although milk is considered among the most complete and nutrition-rich natural foods, the concentration of vitamins and minerals in milk can vary depending on a variety of circumstances. Stelios Couris of the University of Patras and the Foundation for Research and Technology-Hellas (Patras, Greece) has been studying the inorganic elemental composition of a variety of milk samples using LIBS and spoke to Spectroscopy about this research.

Combining multiplex coherent anti-Stokes Raman scattering (MCARS) microscopy with automated data processing enables a simple and more accessible method for label-free bioimaging.

Glycoproteins are becoming popular in the pharmaceutical industry, prompting the need for an effective spectroscopic technique that can differentiate them. SERS is one such technique ideal for glycan analysis for several key reasons, which are discussed here.

Catherine Niu, a professor at the College of Engineering of the University of Saskatchewan in Canada and co-author of this paper, spoke to Spectroscopy about how she and her associates used X-ray photoelectron spectra and near-edge X-ray absorption fine structure (NEXAFS) spectroscopy analysis in their research.

Recently, at the 2022 SciX conference in Covington, Kentucky, Beatriz Fernandez, who is an Associate Professor at the University of Oviedo in Spain, presented, as part of the Technical Program, a discussion regarding the determination of proteins in single cells by ICP-MS using metal nanoclusters as labels of specific recognition reactions. Fernandez spoke to Spectroscopy about her presentation.

Harishchandra Singh, Graham King and associates have employed high energy synchrotron X-ray diffraction (HE-SXRD) experiments and an analytical model in order to predict the yield strength of cerium-modified super duplex stainless steel (SDSS) subjected to various cold- and cryo-deformation. Spectroscopy recently had the opportunity to discuss the experiments and the findings with Singh and King.

In the treatment of tuberculosis (TB), a contagious disease that causes 1.5 million deaths per year globally, early diagnosis is critical in order to control its spread. Unfortunately, standard tuberculosis diagnostic tests, such as sputum culture, can take days to weeks to yield results. In a recent paper, Ubaid Ullah of the Syed Babar Ali School of Science and Engineering in Pakistan and his colleagues demonstrate a quick, portable, easy-to-use, and non-invasive optical sensor based on sputum samples for tuberculosis detection using Raman spectroscopy to detect TB in a patient’s sputum supernatant. Ullah spoke to Spectroscopy about this sensor and its development.

Some macrofungal species are known for their ability to accumulate high concentrations of mercury in their fruit bodies. A recent paper by Simone Braeuer and colleagues of the University of Graz (Austria) and Ghent University (Belgium) discusses an efficient method developed for quantitative mapping of mercury and selenium in mushroom fruit bodies via laser ablation coupled to inductively coupled plasma–mass spectrometry with excellent limits of detection and high spatial resolution (down to 5 µm).
