What to know about Biomimicry in Material Science

Researchers from China and the Netherlands have developed a method to create a strong, biodegradable plastic-like material from corn protein called zein. By mimicking the shearing process spiders use to spin silk, the team produced films that are more durable than standard plant films and effective at preventing food spoilage.

Why it matters

Learning from the natural world has led to a range of useful products, including Velcro, self-cleaning paint, and ultra-strong body armor.

Common ground

And now, a study published in the journal Nature Communications reports that scientists have developed a way to turn a corn protein into a plastic-like material using a method inspired by spider silk.
