Melanin Beyond Pigmentation: A Multifunctional Biomaterial

Melanin is a complex biopolymer found in many organisms, where it protects against UV radiation, scavenges free radicals and even shows bioelectronic activity. For a long time it was understood mainly as a pigment. Today, advances in purification and bioengineering are revealing a much wider role for it as a functional biomaterial.

The same structure that colors skin and tissue also gives melanin its technical value.

Key functional properties

• Broad-spectrum UV-A and UV-B absorption, making it a promising alternative to synthetic UV filters.
• Antioxidant and free-radical scavenging activity that helps protect cells from oxidative stress, including exposure to blue light.
• Semiconductor-like electronic properties that can be tuned for organic electronics and bioelectronic devices.
• Biocompatibility suited to medical coatings and regenerative applications.

Purity makes the difference. Traditional melanin often contains impurities that reduce its effectiveness. Promecens uses proprietary bioengineering and purification processes to deliver high-purity melanin with controlled structural and functional properties.

Applications across industries

• Cosmetics: melanin-based sun care, anti-aging and skin regeneration formulations.
• Medical and pharmaceutical: implant coatings, wound healing support and radioprotective materials.
• Electronics: flexible, biocompatible sensors and organic semiconductors as a biodegradable alternative to conventional components.
• Clean energy: organic photovoltaic components, supercapacitors and protective coatings.

From a biological pigment to an engineered material platform.

With cosmetic, medical, electronics and energy grades available, melanin is becoming one of the most versatile materials in the Promecens portfolio.
