Overview
Researchers at the Shenzhen Institutes of Advanced Technology in China have developed an engineered living material (ELM) based on living mycelium. This material is designed for textile applications, specifically for apparel, and demonstrates properties of self-cleaning and near self-repair. The design also allows for functional customization, such as coloration or UV protection, by incorporating different types of fungi or yeast as 'plug-and-play' add-ons.
Research Context
The development addresses the creation of new textile materials with integrated biological functions. The focus is on leveraging living organisms, in this case, mycelium, to imbue materials with characteristics not typically found in conventional textiles. This aligns with broader research into engineered living materials (ELMs), which integrate biological components into material structures to achieve advanced functionalities.
Approach
The research involved the cultivation and manipulation of living mycelium to form a textile. The material's self-cleaning and near self-repairing capabilities are intrinsic to the living mycelium structure. For customization, the researchers explored a 'plug-and-play' approach, where different strains of fungi or yeast can be integrated into the mycelium textile. This modular strategy allows for the introduction of specific functionalities, such as the ability to impart color or provide UV protective qualities to the resulting textile.
Findings
- The developed textile is constructed from living mycelium.
- This mycelium-based textile exhibits self-cleaning properties.
- The material demonstrates near self-repairing capabilities.
- The textile can be customized for specific functionalities.
- Customization, including coloration or UV protection, is achieved through 'plug-and-play' additions of different fungi or yeast.
Why This Matters
The creation of textiles with integrated self-cleaning and self-repairing functions could potentially reduce maintenance requirements for apparel. The ability to customize material properties like color and UV protection through biological additions offers a flexible and potentially sustainable method for textile production.
Potential Applications
The researchers specifically mention a 'dress made of living mycelium,' indicating a potential application in clothing and fashion. The customizable properties suggest broader applications for functional textiles beyond basic apparel, where integrated self-cleaning, self-repair, coloration, or UV protection would be beneficial.
