BioSteel
From Wikipedia, the free encyclopedia
BioSteel is a trademark name for a high-strength polyamide fiber material made of spider silk-like protein extracted from milk of transgenic goats, made by Nexia Biotechnologies. While the attempt to put spider genes into goats and extract the protein from the milk succeeded, the project so far failed to spin it into the fiber. This and other biopolymers are being researched to provide lightweight, strong, and versatile materials.
