Melanin is an important pigment present in skin, hair, the eye and the brain. Although the constituents of melanin are quite well-known, its detailed structure has so far eluded all types of spectroscopy. Here we use Thioflavin T (ThT) fluorescence to provide evidence for a sheet like structure and reveal for the first time eumelanin’s synthesis kinetics. Using the dye Congo Red, we support the kinetics seen with ThT.
