From melanogenesis to melanin technologies

Abstract

Melanins are a diverse family of natural pigments with a unique combination of optical, electronic, redox, and structural properties that challenge conventional chemical characterisation. This Perspective summarises key insights from the first international interdisciplinary meeting dedicated to melanin, held in Eastbourne, UK and sponsored by the Royal Society. The meeting brought together advances in melanogenesis, pigment evolution, molecular and supramolecular melanin characterisation, alongside emerging applications in energy storage, sensing, coatings, and biodegradable electronics. Here, we highlight the fragmentation of melanin research across disciplines and advocate for a unified, interdisciplinary approach to understanding melanin’s complex chemistry. By integrating perspectives from experts in biology, materials science, paleontology, device physics and chemistry, we propose a roadmap for future melanin research, towards melanin-based functional devices and technologies.
