Living Fungus Fabric Heals Itself and Fights UV Rays

Your next jacket might be alive, and it could heal its own tears.

Researchers at the Chinese Academy of Sciences created a fabric made from living fungus that stays alive even after manufacturing. The material can regrow its surface when damaged, essentially repairing itself without human intervention.

The secret lies in mycelium, the thread-like network that makes up most mushrooms. Unlike existing mushroom-based leather alternatives that use dead fungal material, this textile remains living and functional. The team soaked dense mats of naturally interwoven mycelium in glycerol, creating a soft, flexible fabric that doesn't kill the organism.

When the researchers feed it nutrients, the fabric sprouts fuzzy fungal filaments across its surface. This self-renewal process means damage doesn't have to be permanent.

The living material can also host other helpful microbes. By embedding pigment-producing yeast, the team created colorful patterns. Adding a melanin-producing fungus gave the textile built-in ultraviolet protection.

Research professor Bolin An and his colleagues wanted to prove that mycelium could remain "alive and programmable while still behaving as a freestanding, flexible textile." Their visually striking results suggest living materials can gain new abilities even after creation.

The Bright Side

Before you get too excited about living jeans, this fabric isn't ready for everyday wear. It needs careful storage to prevent contamination and completely biodegrades within six weeks.

But that short lifespan makes it perfect for products we don't want lasting forever. Think disposable packaging that naturally disappears or temporary art installations that clean themselves.

An envisions even bigger possibilities: "A living curtain could provide passive ultraviolet shielding, self-cleaning surfaces or, in the future, even environmental sensing or air purification." Imagine window treatments that actively filter air or protect you from sun damage.

Researchers at the University of Vienna who weren't involved in the study praised the technical achievement. They noted that "the novelty lies in bringing them together within a single living-material platform," even though the individual components already existed.

The technology won't solve fashion's sustainability crisis alone, since that problem stems more from fast-fashion business models than materials. But it opens doors to rethinking how we design products meant to be temporary.

The future of materials might not just be sustainable but actually alive.
