Ultrafast Radical Photogeneration Pathways in Eumelanin†
Photochemistry and Photobiology, 2022 AbstractEumelanin is a ubiquitous biological pigment that rapidly and efficiently deactivates excited states created by UV or visible radiation. Paradoxically, photoirradiation of eumelanin also generates radicals and harmful reactive oxygen species, but the relationship between these pathways and excited‐state deactivation is uncertain.
