Click on PDF to download from Part 3 2023: Researchers reported a production method for spider silk fibers from gene-edited transgenic silkworms for a sustainable alternative material six times stronger than Kevlar. Now, researchers had successfully gene-edited silkworms to produce spider silk that’s six times stronger than Kevlar, the material used in bulletproof vests. This heavy-duty fiber could one day be used for surgical sutures, wound dressings, armored vests and structural materials for vehicles.
