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

Nanomaterials, 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.
