2007 journal article
The surface oxidation potential of melanosomes measured by free electron laser-photoelectron emission microscopy
PHOTOCHEMISTRY AND PHOTOBIOLOGY, 83(3), 692–697.
MeSH headings : Animals; Cattle; Hair / cytology; Hair / ultrastructure; Humans; Iron / metabolism; Iron Chelating Agents / pharmacology; Melanosomes / chemistry; Microscopy / instrumentation; Microscopy / methods; Nanostructures; Oxidation-Reduction; Pigment Epithelium of Eye / ultrastructure; Potentiometry; Sepia; Silicates; Spectrum Analysis; Titanium
TL;DR:
The surface oxidation potential of iron in human melanosomes in both the eye and brain is insensitive to bound Fe(III) up to saturation, suggesting that the metal is bound to the interior of the granule.

2006 journal article
Age-dependent photoionization thresholds of melanosomes and lipofuscin isolated from human retinal pigment epithelium cells
PHOTOCHEMISTRY AND PHOTOBIOLOGY, 82(6), 1475–1481.
MeSH headings : Adolescent; Aged; Humans; Light; Lipofuscin / metabolism; Lipofuscin / radiation effects; Melanosomes / metabolism; Melanosomes / radiation effects; Melanosomes / ultrastructure; Microscopy, Electron, Scanning; Middle Aged; Pigment Epithelium of Eye / cytology; Pigment Epithelium of Eye / physiology; Pigment Epithelium of Eye / radiation effects; Retina / growth & development; Spectrophotometry
TL;DR:
The data suggest that thin deposits of lipofuscin on the surface of retinal pigment epithelium melanosomes are common in the aged eye and that this renders the melanosome more pro-oxidant.

Photoionization thresholds of melanins obtained from free electron laser-photoelectron emission microscopy, femtosecond transient absorption spectroscopy and electron paramagnetic resonance measurements of oxygen photoconsumption
PHOTOCHEMISTRY AND PHOTOBIOLOGY, 82(3), 733–737.
MeSH headings : Electron Spin Resonance Spectroscopy; Melanins / chemistry; Microscopy, Electron; Oxygen / chemistry; Photochemistry; Skin Neoplasms / etiology; Spectrophotometry, Ultraviolet; Spectrum Analysis / methods
TL;DR:
The lower ionization potential observed for pheomelanin could be an important part of the explanation for the greater incidence rate of UV-induced skin cancers in red-haired individuals.

2006 journal article
The surface oxidation potential of human neuromelanin reveals a spherical architecture with a pheomelanin core and a eumelanin surface
PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA, 103(40), 14785–14789.
author keywords: free electron laser; oxidative stress; photoelectron imaging; substantia nigra; Parkinson's disease
MeSH headings : Animals; Brain Chemistry; Cattle; Humans; Melanins / chemistry; Melanins / radiation effects; Microscopy, Atomic Force; Microscopy, Electron, Scanning; Oxidation-Reduction; Sepia; Substantia Nigra / chemistry; Substantia Nigra / ultrastructure; Surface Properties; Ultraviolet Rays
TL;DR:
Neuromelanin isolated from the substantia nigra region of the human brain was studied by scanning probe and photoelectron emission microscopies and reveals that NM granules are comprised of spherical structures with a diameter of ≈30 nm, similar to that observed for Sepia cuttlefish, bovine eye, and human eye and hair melanosomes.

Oxidation potentials of human eumelanosomes and plheomelanosomes
PHOTOCHEMISTRY AND PHOTOBIOLOGY, 81(1), 145–148.
TL;DR:
The effect of added melanosomes on the reduction of Fe(III)-cytochrome showed pheomelanosome are stronger reducing agents than eumelanosomes, consistent with the measured oxidation potentials.

Photoionization threshold of eumelanosomes determined using UV free electron laser - Photoelectron emission microscopy
Samokhvalov, A., Garguilo, J., Yang, W. C., Edwards, G. S., Nemanich, R. J., & Simon, J. D. (2004, October 21).
TL;DR:
The UV-FEL-PEEM images collected on human eumelanosomes isolated from black hair show that the organelle is photoionized by UV-B radiation, providing new insight into the origin of the differences between the photoionization and oxygen photoconsumption action spectra for eumELanins.
