Physics Colloquium: “Transient Absorption Spectroscopy & Imaging with Heme Proteins: Endogenous Contrast for Redox, Oxygenation, & More”
Jesse Wilson Colorado State University, Electrical & Computer Engineering Abstract: Heme proteins contain an iron-porphyrin group, which plays a central role in oxygen transport, electron transfer, and catalysis in a wide range of organisms. Their unique redox- and oxygen-sensitive optical absorption spectra form the basis for technologies like pulse-oximetry devices and provided critical clues that […]
