Swiss researchers at Empa have developed a novel material derived from the split-gill mushroom (Schizophyllum commune) that is flexible, biodegradable, edible, and remains biologically active.

This innovation, termed Living Fiber Dispersions (LFD), utilizes the mycelium (the root-like structure of fungi) processed into a gel-like substance without destroying its biological functions. As a result, the material continues to produce beneficial molecules over time, enhancing its properties.

LFD exhibits high tensile strength and can be molded into various forms, making it suitable for applications such as compostable bags that decompose alongside their contents.

Its emulsifying properties improve over time, suggesting potential uses in the food and cosmetic industries, positioning it as a proper alternative to plastic.

Materials scientist Ashutosh Sinha, from Empa, said:

"The fungus uses this extracellular matrix to give itself structure and other functional properties, why shouldn't we do the same?"

The material's adaptability extends to electronics, where it can be used to produce biodegradable sensors and batteries.

Its responsiveness to environmental factors like moisture allows for dynamic applications, including smart packaging that reacts to its surroundings and even clothes that can repair the damage and can be used to design the most advanced robots in the future.

By utilizing the natural properties of S. commune, this development offers a sustainable alternative to traditional plastics, with the added benefits of being edible and environmentally friendly.
