Researchers have engineered a textile material using the parasitic fungus Cordyceps militaris that can clean itself and repair damage autonomously. The fabric represents a new category of living material that combines biological function with textile performance.
The team grew Cordyceps militaris mycelium into fiber structures, then wove these biological filaments into functional cloth. Unlike conventional synthetic fabrics, this living textile contains active fungal cells capable of responding to environmental conditions. The material is fully biodegradable, breaking down naturally when no longer needed rather than accumulating in landfills as plastic-based textiles do.
The self-cleaning capability emerges from the fungus's natural metabolic processes. When contaminated, the living fabric can generate compounds that break down dirt and organic stains without requiring chemical detergents. The repair function works similarly. Damage to the material triggers a biological response where the fungal cells proliferate to fill tears and restore structural integrity, mimicking how living organisms naturally heal wounds.
Researchers demonstrated adaptability by incorporating different microbes into the fungal matrix. These microbial partners can be selected to confer specific properties depending on intended use. Applications could range from clothing that resists odor and bacterial growth to industrial textiles with specialized chemical resistance.
The work builds on recent advances in mycelium-based materials. Scientists have previously created leather alternatives, packaging materials, and insulation from fungal mycelium. This textile project extends that research into functional garments with genuine biological activity.
Challenges remain before commercial production becomes feasible. The living fabric requires appropriate moisture and temperature conditions to maintain viability. Scaling production from laboratory samples to industrial quantities presents technical hurdles. Consumer acceptance of clothing that contains living organisms may also require cultural adaptation.
The researchers did not specify publication details in available reporting, though the work appears connected to New Scientist's coverage of biomaterial innovations. The fung
