At Pittcon, Spectroscopy sat down with Christian Huck of the University of Innsbruck to talk about how NIR and imaging spectroscopy are being used in food and bioanalysis, and where this industry is heading in the future.

Tip-enhanced Raman spectroscopy (TERS) employs localized surface plasmon resonance at the apex of a sharp scanning probe microscopy tip to overcome the diffraction limit inherent in conventional Raman spectroscopy, allowing researchers the ability to access spatial resolutions down to the nanometer scale. This technique has established itself as a powerful tool in nanoscale chemical analysis, delivering previously unachieved spatial resolution with superior molecular sensitivity and chemical specificity.

An effective technique used in the examination of iron atom electronic environments in both biomolecular molecules and whole animal studies, Mössbauer spectroscopy, because of its sensitivity to nuclear hyperfine interactions, yields incredibly accurate data regarding the electronic and magnetic states of nuclei, chemical bonds, and the local electronic environment structure around iron atoms.

Yesterday, at 5:00 pm in Ballroom East, the Wallace H. Coulter Lecture took place, and it was delivered by Cato T. Laurencin, MD, PhD, who is well-known as a scientist and entrepreneur with an extensive career in regenerative engineering. His lecture highlighted the work he and his team has done in this space.

“Atomic Perspectives,” provides tutorials and updates on new analytical atomic spectroscopy techniques in a broad range of applications, including environmental analysis, food and beverage analysis, and space exploration, to name a few. Here, we present a compilation of some of the most popular columns.

Researchers from Jiangsu University and Jimei University have developed an AI-powered detection system using near-infrared spectroscopy and a convolutional neural network long short-term memory (CNN-LSTM) model to accurately identify petroleum contamination in edible oils for improving food safety and quality control.
