Spectroscopy
The authors describe several applications of FT-IR spectroscopy in the biomedical sciences, including characterization of healthy and neoplastic human skin samples affected by two kinds of cancers, and examination of liver damage and regeneration caused by carbon tetrachloride.
High-Speed Laser MS for Precise, Prep-Free Environmental Particle Tracking
April 21st 2025Scientists at Oak Ridge National Laboratory have demonstrated that a fast, laser-based mass spectrometry method—LA-ICP-TOF-MS—can accurately detect and identify airborne environmental particles, including toxic metal particles like ruthenium, without the need for complex sample preparation. The work offers a breakthrough in rapid, high-resolution analysis of environmental pollutants.
