Chinese researchers have engineered a textile that stays alive after it leaves the lab, opening a new front in the search for garments that clean, repair and eventually dispose of themselves.
A team led by scientists at the Shenzhen Institutes of Advanced Technology built the material from Cordyceps militaris, a thread-forming fungus long used in traditional Chinese medicine and commonly known as caterpillar fungus. Rather than weaving spun fibers, the researchers grew dense mats of mycelium, the branching filaments that make up the bulk of a fungus, and let them knit naturally into cohesive sheets. Soaking the mats in glycerol, a syrupy plasticizer, softened the material into a flexible, wearable textile without killing the organism inside it, according to a study published in the journal Science Advances.

The result is what scientists call an engineered living material, a category that has struggled to scale microscopic living cells into durable, functional structures large enough to be useful. Because the fungus remains alive, the fabric can be fed nutrients that prompt it to grow a fresh layer of fuzzy filaments across damaged areas, effectively renewing its own surface. The living platform can also host other engineered microorganisms after the fact: a pigment-producing yeast embedded in the material created colored patterns, while a second fungus that naturally generates melanin gave the textile ultraviolet protection. Researchers say the approach demonstrates that new functions can be added to the fabric even after it has already been manufactured.
Environmental testing found the material broke down within roughly 41 days, according to the Shenzhen-led study, a degradation window researchers say could support circular fashion models in which garments are designed for reuse or full biodegradation rather than landfill disposal. Bolin An, a research professor at the Chinese Academy of Sciences and a co-author of the work, said the goal was to determine whether a mycelium-based material could stay alive and programmable while still functioning as a freestanding, flexible textile.

Turning mushroom material into consumer products is not new; mycelium has already been developed into leather substitutes, packaging, insulation and building materials, including for luxury fashion accessories. But those applications typically rely on dead, processed fungal matter, which limits the range of properties the material can display, the researchers say. Keeping the fungus alive introduces its own complications, including the need for specific storage conditions to prevent contamination, and researchers caution the fabric is not ready for retail shelves.
Outside scientists offered a measured assessment of the work’s significance. Alexander Bismarck and Mitchell Jones of the University of Vienna’s Polymer and Composite Engineering Group, who were not involved in the study, said the research proves a living textile is technically achievable but does not by itself establish that such material is safer, better performing or preferable to conventional fabrics. They noted that most of the individual components behind the platform were already established elsewhere, with the innovation lying in combining them within a single living-material system.
Given its roughly six-week degradation timeline, researchers see the fabric as better suited to short-lived applications such as disposable packaging, temporary installations or event structures than to durable apparel like winter coats. An suggested a living curtain made from the material could one day provide passive ultraviolet shielding and self-cleaning surfaces, with future versions potentially capable of environmental sensing or air purification. Scientists also cautioned that materials innovation alone will not resolve the fashion industry’s broader waste problem, much of which stems from fast-fashion production models and consumer disposal habits rather than the fabrics themselves.
The Shenzhen team has already produced demonstration pieces, including a dress and a full-length garment, to illustrate how the living fabric behaves once assembled into wearable form. For now those pieces remain research prototypes rather than commercial samples, and the researchers say further work is needed to stabilize the material’s shelf life outside controlled laboratory conditions before any textile or packaging application could move toward market testing.
