Chemical and Physical Analysis of Melanin in Complex Biological Matrices
(2014)Melanin is a ubiquitous biological pigment found in bacteria, fungi, plants, and animals. It has a diverse range of ecological and biochemical functions including display, evasion, photoprotection, detoxification, and metal ... -
Melanin Chemistry Revealed by Excited State Dynamics and the Resulting Biological Implications
(2014)Dermatopathologists need more reliable tools for analyzing biopsies of lesions that are potentially melanomas and determining the best treatment plan for the patient. Previously inaccessible, the chemical and physical properties ... -
The Ultraviolet Absorption Coefficient of Melanosomes Decreases with Increasing Pheomelanin Content
(2010)Uveal melanosomes from the iridal stroma contain both eumelanin and pheomelanin, the ratio of which varies with iris color. Herein, we report the absorption coefficient at lambda = 244 nm for individual human iridal stroma ... -
Ultraviolet Absorption Coefficients of Melanosomes Containing Eumelanin As Related to the Relative Content of DHI and DHICA
(2010)Central to understanding the photochemical function(s) of melanosomes is the determination of their absorption properties and an understanding of how the absorption varies with the molecular composition of melanin. Herein, ...
