The detection of a new transient species in photoirradiated natural and synthetic melanins is
reported. This species decays rapidly at both ambient and cryogenic temperatures and has …

The variation with temperature, pH and light of the ESR signal of hydrated melanin powders
from Japanese black hair has been studied. An explanation of the results is proposed on the …

The electron spin resonances (ESR) of several native and modified melanins have been
determined. Melanins isolated from black wool and synthesized from 3, 4-dihydroxyl-L …

Electron spin resonance measurements on aerated melanin suspensions during
photoirradiation show changes in the microwave saturation of melanin free radicals and …

Publisher Summary Melanins contain free radicals under all known experimental conditions.
The free-radical content is sensitive to light, reducing and oxidizing equivalents, and other …

Formation of light-induced free radicals from natural eumelanin (from bovine eyes) and
synthetic melanin (from oxidation of 3, 4-dihydroxyphenylalanine) has been studied by …

The presence of unpaired electrons in melanin may be readily understood if it is supposed
that melanin is in effect a one-dimensional semiconductor, any bound protons acting as …

Melanin is a ubiquitous biological pigment with unusual physicochemical properties. This
paper emphasizes selected aspects of melanin research in which significant contributions …

Rose Bengal is shown to photosensitize free‐radical production and oxygen consumption in
solutions of melanin from autooxidation of 3, 4‐dihydroxyphenylalanine (DOPA). In …

The first quantitative measurements of the wavelength dependence of oxygen consumption
in systems containing eumelanin (from bovine eyes) and synthetic DOPA melanin are …
