Biological Materials Processing: Time-Tested Tricks for Sustainable Fiber Fabrication

Area of Science:

• Materials Science
• Biomaterials Engineering
• Sustainable Chemistry

Background:

• Growing demand for sustainable materials necessitates novel fabrication approaches.
• Nature provides diverse examples of high-performance biopolymeric fibers with unique properties.

Purpose of the Study:

• To review and synthesize natural strategies for sustainable polymeric fiber fabrication.
• To identify common principles across diverse biological systems for bioinspired design.
• To explore the potential for technology transfer in synthetic materials.

Main Methods:

• Review of physical and chemical aspects of materials processing in natural systems.
• Analysis of model systems: spider silk, mussel byssus, velvet worm slime, hagfish slime, mistletoe viscin.
• Identification of common and divergent fabrication strategies.

Main Results:

• Common strategies include stimuli-responsive building blocks, concentrated fluid precursors (coacervates, liquid crystals), and chemical/physical triggers for solidification.
• These principles are transferable to synthetic systems due to extracellular formation.
• Diverse biopolymeric fibers share fundamental processing strategies.

Conclusions:

• Nature's methods offer a blueprint for sustainable synthetic material fabrication.
• Bioinspired design can lead to advanced polymeric fibers with excellent properties.
• Ongoing research focuses on mimicking natural systems like spider silk and mussel adhesive proteins.
