Chinese scientists have engineered wearable textiles from Cordyceps militaris — the caterpillar fungus long used in traditional Chinese medicine — creating fabrics capable of self-cleaning, regenerating, and degrading within 41 days. The breakthrough, published in the journal Science Advances on Friday, 27 July 2026, marks a significant step toward circular fashion and biodegradable materials at scale.

What the researchers built

A research team led by the Shenzhen Institutes of Advanced Technology developed a method to fabricate engineered living materials (ELMs) using the threadlike structures — known as hyphae — produced by Cordyceps militaris. The fungus's natural ability to form dense, fibrous networks made it a practical candidate for scaling microscopic living cells into large, durable textile structures, according to the study.

The team also demonstrated that the living fabric could be customised through the introduction of other microorganisms — including Aspergillus niger — to add properties such as colour pigmentation or protection against ultraviolet (UV) radiation.

Why it matters

Scaling living cells into functional, wearable materials has been a persistent bottleneck for the ELM field. Most prior efforts produced samples too fragile or too small for practical use. The Shenzhen-led approach reportedly addresses this by leveraging the structural robustness of fungal hyphae, which self-organise into textile-grade fibre networks without synthetic binders.

Environmental assessments confirmed the material fully degraded within 41 days, a timeline that positions it as a viable input for circular fashion — clothing systems designed for reuse, recycling, or safe composting at end of life.

The competitive backdrop

The living-materials race has drawn academic and commercial interest globally, with startups and university labs in the United States, Europe, and Asia exploring mycelium-based leather and packaging alternatives. What distinguishes the Shenzhen Institutes of Advanced Technology approach is the retention of biological activity — the fabric remains alive and functional post-fabrication, enabling self-repair and programmable surface properties that static bio-based materials cannot replicate.

The use of Cordyceps militaris — a species with an established supply chain in China due to its role in traditional medicine — also offers a potential sourcing advantage over more exotic fungal strains used in Western mycelium-textile programmes.

What's next

The study's authors, led by researcher Li Ke, did not specify a commercialisation timeline, and the technology remains at the laboratory stage. Key open questions include whether the living properties can be preserved through industrial dyeing, cutting, and stitching processes, and whether the 41-day degradation window can be tuned for longer-wear applications. Fashion brands and biodegradable packaging manufacturers are among the sectors most likely to watch this research for licensing or partnership opportunities.
