Melanins represent one of the most ancient and important group of natural macromolecular
pigments. They have multiple biological roles in almost all organisms across the Phyla …

Melanin and melanoma tumors are two fields of increasing interest in biomedical research.
Melanins are ubiquitous biopigments with adaptive value and multiple functions, and occur …

Melanins (eumelanin, pheomelanin, and allomelanin) represent a very, if not the most,
important group of biological pigments. Their biological roles are multiple, from …

Eumelanin is the active ingredient in skin pigment found in human beings. It is also present
in animals, plants, and some bacteria and fungi. However, there are still open questions …

Melanin pigment and melanoma are two fields of increasing interest and relevance in
biomedical research. Melanins are ubiquitous biopigments with strong adaptive value and …

In this article, we review the current state of knowledge concerning the physical and
chemical properties of the eumelanin pigment. We examine properties related to its …

We discuss recent progress towards the establishment of important structure–property–
