Electrochemical synthesis of melanin free-standing films [PDF]

, 2005
Free-standing melanin films were successfully synthesised electrochemically from dopa. The Optimum synthetic conditions such as pH, concentration and current were determined, and it was found that free-standing film,.; could only be formed when ITO glass

Subcellular Compartmentalization and Trafficking of the Biosynthetic Machinery for Fungal Melanin

Cell Reports, 2016
Protection by melanin depends on its subcellular location. Although most filamentous fungi synthesize melanin via a polyketide synthase pathway, where and how melanin biosynthesis occurs and how it is deposited as extracellular granules remain elusive ...

Radical-Enriched Artificial Melanin [PDF]

, 2020
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 ionizing radiation protection, including X-rays and gamma

Radiofrequency Irradiation Mitigated UV-B-Induced Skin Pigmentation by Increasing Lymphangiogenesis

Molecules, 2022
Dermal macrophages containing melanin increase skin pigmentation since dermal melanin removal is slower than epidermal melanin removal. Lymphatic vessels are also involved in melanin clearance. We evaluated whether radiofrequency (RF) irradiation induced

The Melanin Biosynthesis Genes of Alternaria alternata Can Restore Pathogenicity of the Melanin-Deficient Mutants of Magnaporthe grisea

Molecular Plant-Microbe Interactions, 1997
The phytopathogenic fungi Magnaporthe grisea and Alternaria alternata produce melanin via the polyketide biosynthesis, and both fungi form melanized colonies. However, the site of melanin deposition and the role of melanin in pathogenicity differ between
