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.

The Coblentz Society created the Clara Craver Award to recognize young individuals who have made significant contributions in applied analytical vibrational spectroscopy. The work may include any aspect of infrared (IR), terahertz (THz), or Raman spectroscopy in applied analytical vibrational spectroscopy. This year’s recipient, Ishan Barman, is an Associate Professor in the Department of Mechanical Engineering at the Johns Hopkins University with joint appointments in Oncology and Radiology and Radiological Science.

The AES Lifetime Achievement Award is given for exceptional career contributions to the fields of electrophoresis, electrokinetics, and related areas. This year’s recipient, James Landers of the University of Virginia, recently published (along with his colleagues) a paper illustrating a technique for fabricating electrophoretic microdevices for fluorescence detection.

Earlier this year, Spectroscopy spoke to Maria Montes-Bayón of the Faculty of Chemistry at the University of Oviedo (Asturias, Spain) regarding her work with single cell inductively coupled plasma mass spectrometry (ICP-MS) to study the uptake and apoptotic status of nanoplatinum (IV) treated cells, specifically selenized yeast.

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.
