CHARGE TRANSPORT BEHAVIOR IN NATURAL SEPIA MELANIN NANOGRANULES
Sepia eumelanin, a natural biopigment extracted from cuttlefish ink, has attracted growing interest as a sustainable material for organic electronics. Its nanogranular structure, composed of DHI and DHICA monomers, presents unique charge transport characteristics influenced by hydration and measurement scale. While prior studies have explored its mixed
