Near-infrared (NIR) spectroscopy provides a rapid and cost-effective method for food-allergen detection. Over 15 million people in the US have a food allergy. Even trace amounts of a substance can ...

Lisa Wu, undergraduate student in Agricultural and Biological Engineering at the University of Illinois, conducted research on detecting food allergens with near-infrared spectroscopy. Credit: College ...

Food allergies pose a significant health risk, resulting in numerous hospitalizations every year, as even trace amounts of allergens can trigger severe reactions. Cross-contamination of food products ...

NIR spectroscopy concerns the analysis of how NIR light and matter interact. In spectroscopic analysis, light is determined by the wavelength, not by the applied energy. The wavelength of light is ...

Infrared vibrational spectroscopy could enable the production of high-resolution maps of molecules inside live cells and cell organelles. A new study from Helmholtz-Zentrum Berlin (HZB) and Humboldt ...

PiFM and PiF-IR are the next generation of infrared spectroscopy techniques. PiFM brought a major shift to atomic force microscopy by adding chemical mapping capabilities. PiF-IR, its sister technique ...

A promising microspectroscopy technique has just become far more promising thanks to an improvement that increases the technique’s sensitivity and spatial resolution. The advance, which combines ...

All fibers were analyzed directly without additional modification or sampling accessories. The O-PTIR spectra resemble transmission-like IR spectra in non-contact (far-field) mode. Through spatially ...

Research into spectroscopy in the mid-IR spectral region has made several recent breakthroughs, spurred by potential uses of the technique in biophotonics and medical imaging. But development of ...

URBANA, Ill. – Food allergies pose a significant health risk, resulting in numerous hospitalizations every year, as even trace amounts of allergens can trigger severe reactions. Cross-contamination of ...
