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.

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). Braeuer spoke to Spectroscopy about this paper.

Karen Faulds of the University of Strathclyde co-authored a paper where SESORS signals could be detected from nanotags at depths down to 48 mm for the first time using a handheld spatially offset Raman (SORS) instrument.

Spray paint is often used by vandals for creating graffiti, as well as for criminals to leave signs, messages, and blots to conceal the left traces at the scene of their efforts. Rajinder Singh and his colleagues in the Department of Forensic Science at Punjabi University (Punjab, India) have used attenuated total reflectance Fourier transform infrared (ATR-FT-IR) spectroscopy for nondestructive analysis of 20 red spray paints of different manufacturers, which could possibly be encountered at a crime scene, particularly in case of vandalism. Singh spoke to Spectroscopy about the findings, and the paper that resulted from their efforts.

Their findings reveal the potential of BRELIBS in conducting elemental analysis on transparent materials. Spectroscopy recently spoke to Abdel-Harith about this work.

Meat fraud has emerged as a growing concern globally. The adulteration, substitution, or mislabeling of meat products has resulted in negative economic effects, such as unfair competition in the global marketplace, as well as ethical concerns, because consumers want to know what is in the meat they are consuming. Ismail H. Boyaci of Hacettepe University and his team have explored using laser-induced breakdown spectroscopy (LIBS) for protein-based analysis and the identification of meat species. Spectroscopy recently spoke to Boyaci about this work.
