Nanospheres: Selective Coloration of Melanin Nanospheres through Resonant Mie Scattering (Adv. Mater. 22/2017)

Melanin, a major component in brunette hairs, is commonly black. However, hairs appear brown when they are exposed to direct sunlight. Inspired from the selective coloration of hair, Shin-Hyun Kim and co-workers study the coloration of artificial melanin-like nanospheres in article number 1700256. Special inks are formulated based on the size-dependent coloration property of the nanospheres.
