Colloidal crystals have been used to develop structural colors. However, incoherent scattering causes the colors to turn whitish, reducing the color saturation. To overcome the problem, light-absorbing additives have been incorporated.

Determination of eumelanin in human urine
Pigment Cell Research, 2006SummaryNormal and malignant melanocytes produce melanins and melanin‐related metabolites, most of which are retained in the cells but some are secreted into the blood and then excreted in the urine. In this study, we developed a method to measure levels of eumelanin in urine samples and evaluated its clinical significance in comparison with the melanin‐

Fluorescence spectroscopy of eumelanins
IEEE Journal of Quantum Electronics, 1984The fluorescence spectra from different forms of melanin, excited by an argon-ion laser at 488 nm wavelength were measured. The fluorescence intensity and maxima were found to be dependent on the melanin concentration. The location of the fluorescence maxima depends on the type of melanin and its environment.

Eumelanin-like Poly(levodopa) Nanoscavengers for Inflammation Disease Therapy.
BiomacromoleculesIn the current years, polydopamine nanoparticles (PDA NPs) have been extensively investigated as an eumelanin mimic. However, unlike natural eumelanin, PDA NPs contain no 5,6-dihydroxyindole-2-carboxylic acid (DHICA)-derived units and may be limited in ...

Reexamination of the structure of eumelanin
Biochimica et Biophysica Acta (BBA) - General Subjects, 1986The generally accepted concept that the black melanin eumelanin is made mostly from 5,6-dihydroxyindole but not from 5,6-dihydroxyindole-2-carboxylic acid (DHIC) was reexamined by comparison of synthetic and natural eumelanins. The analytical methods used were elemental analysis and determination of the carboxyl group by acid treatment to yield CO2 and

The supramolecular structure of melanin pigments is characterized by a high concentration of radical species. Therefore, the energetics of the radical formation in melanin building blocks is key for understanding the structure and the electronic properties of the pigments at the molecular level. Nevertheless, the radical energetics of even the simplest
