High conductivity Sepia melanin ink films for environmentally benign printed electronics. [PDF]
Proc Natl Acad Sci U S A, 2022 Melanins (from the Greek μέλας, mélas, black) are bio-pigments ubiquitous in flora and fauna. Eumelanin is an insoluble brown–black type of melanin, found in vertebrates and invertebrates alike, among which Sepia (cuttlefish) is noteworthy.

Electronic Transport in the Biopigment Sepia Melanin [PDF]
ACS Applied Bio Materials, 2020 Eumelanin is the most common form of the pigment melanin in the human body, with diverse functions including photoprotection, antioxidant behavior, metal chelation, and free radical scavenging. Melanin also plays a role in melanoma skin cancer and Parkinson's disease.

Effect of UV irradiation on free radicals in synthetic melanin and melanin biopolymer from Sepia officinalis – EPR examination [PDF]
Nukleonika, 2015 Free radicals in synthetic melanin and melanin from Sepia officinalis were studied by electron paramagnetic resonance (EPR) spectroscopy. The effect of time of ultraviolet (UV) irradiation on free radicals in these melanins was tested.

Effect of Melanomal Proteins on Sepia Melanin Assembly [PDF]
Journal of Macromolecular Science - Physics, 2015 Melanins are phenol-based pigments with the potential for widespread applications, including bioelectronics and tissue engineering. The concentration-dependent structural transition of sepia melanin in water is analyzed. This biopolymer at high concentration gives the well-known nanospheres, whereas sample dilution gives unforeseen nanofibres ...

Morphological and Chemical Composition Characterization of Commercial Sepia Melanin [PDF]
American Journal of Nanomaterials, 2015 Melanins are difficult to characterize because of their intractable chemical properties and the heterogeneity in their structural features. Melanin pigments, in fact, are composed of many different types of monomeric units that are connected through strong carbon-carbon bonds.
