TLDR
One of the most unusual features of melanin is the presence of stable persistent radicals as mentioned in this paper, which has been reported to relate to the properties of the melanin's melanin pigments.Abstract:
Melanin is a class of ubiquitous, heterogeneous, polymeric pigments. One of the most unusual features of melanin is the presence of stable persistent radicals, which has been reported to relate to ...read more
