Spider silk has long been admired by material scientists for its unique combination of high-performance mechanical properties including toughness, strength, lightness, and flexibility. Unfortunately, no one has been able to produce this wonder material in commercial quantities. Nexia is the only company which has successfully produced fibres from recombinant spider silk and is currently in the process of developing commercial quantities of BioSteel using its proprietary transgenic goat technology. Medical device applications of BioSteel-M include wound closure systems like microsutures, surgical meshes, and artificial ligaments such as anterior cruciate ligaments in the knee (ACL). Industrial BioSteel-I applications may include consumer products such as biodegradable fishing line, tennis strings and military applications (soft body armour). Using its transgenic platform technology, Nexia also produces biopharmaceuticals, where it uses its transgenic production system to produce complex proteins that can be used as drugs.
