Melanin and Melanin-Like Hybrid Materials in Regenerative Medicine [PDF]

open access: yesNanomaterials, 2020
Melanins are a group of dark insoluble pigments found widespread in nature. In mammals, the brown-black eumelanins and the reddish-yellow pheomelanins are the main determinants of skin, hair, and eye pigmentation and play a significant role in photoprotection as well as in many biological functions ensuring homeostasis.

Synthetic Porous Melanin

open access: yesJournal of the American Chemical Society, 2021
Commonly known as a skin pigment, melanin has a vital role in UV radiation protection, primarily acting as a radical scavenger. However, a lesser known natural property of melanin, observed in some melanized organisms, is its capacity to adsorb toxins, including metals and organic molecules.
