Cuong Cao from the Institute for Global Food Security at the School of Biological Sciences of Queen’s University in Belfast and his team of researchers conducted a preliminary exploratory study and detected the presence of MPs by automated Raman spectroscopy and subsequently NPs by using nanoparticle-on-film SERS (NPoF SERS) substrate released from chewing gum base plastic, a technique that has potential in screening a varied array of environmental pollutants, as well as a point-of-site tool when coupled with a handheld Raman instrument. Cao spoke to Spectroscopy about this work, and the resulting paper.

The introduction of miniaturized near-infrared (NIR) instruments has transformed the use of technology in the field of forensics. A recent research paper examines the main aspects and provides a comprehensive, critical review of this equipment.

The Institute of Forensic Science and Criminology of Bundelkhand University (Jhansi, India) has used Fourier transform infrared spectroscopy (FT-IR) combined with principal component analysis (PCA) and partial least square regression (PLSR) to investigate adulteration in petroleum products and to design an adulterant profiling method.

Researchers at Texas A&M University (College Station, Texas) presented a novel approach to forensic hair analysis that is based on high-throughput, nondestructive, and non-invasive surface-enhanced Raman spectroscopy (SERS) and machine learning (ML). Using this approach, Dmitry Kurouski and his team investigated the reliability of the detection and identification of artificial dyes on hair buried in three distinct soil types for up to eight weeks.

A multi-organizational team, believing that a reason for slow adoption is a lack of evidence that data taken on one spectrometer can transfer across to data taken on another spectrometer to provide consistent diagnoses, investigated multi-center transferability using human oesophageal tissue. By using a common protocol, the researchers aimed to minimize the difference in machine learning performance between centers.

A joint French-Canadian study examined the ripening process of commercially popular Comté and cheddar cheeses, which are widely consumed in those countries, utilizing mid-infrared (mid-IR) and synchronous fluorescence spectroscopy (SFS) in their analysis.

A recent article authored by scientists from the Institute of Sport and Preventive Medicine, part of the University of Saarland (Saarbrücken, Germany), discusses their investigation of the absolute and relative test-retest reliability of the Moxy Monitor, as well as their investigations into side differences of oxygen saturation at the vastus lateralis muscle of both legs in male cyclists.

Evans of the Wellman Center for Photomedicine at Massachusetts General Hospital (Charlestown, Massachusetts) discusses his recently published study demonstrating sparse spectral sampling stimulated Raman scattering.

In this equipment roundup, the editors of Spectroscopy feature new instruments from SCIEX and ClearPoint.

Researchers have recently investigated the microdistribution of a variety of trace elements in dirty and washed toenails (and the speciation of arsenic specifically in situ) using synchrotron X-ray fluorescence microscopy (XFM) and laterally resolved X-ray absorption near edge spectroscopy (XANES).

Exum Industries, producers of the first laser ablation laser ionization time of flight mass spectrometer (LALI-TOF-MS), announced a partnership with Edge Scientific to better promote and distribute their products.

Using logistics regression on laser-induced breakdown spectroscopy (LIBS) spectra of plasma samples collected pre- and post- Covid-19 pandemic from donors known to have developed various levels of antibodies to the SARS-Cov-2 virus, University of Massachusetts physics professor Nourddine Melikechi’s research team has shown that relying on the levels of sodium (Na), potassium (K), and magnesium (Mg) together is more efficient at differentiating the two types of plasma samples than any single blood metal alone. We spoke to Melikechi about this research.

Portable spectrometers allow the equipment to be taken to the sample, as opposed to the sample to the spectrometer, moving the laboratory to the point of need.
