Kraig Labs develops ‘underwater’ silk inspired by caddisfly
Kraig Biocraft Laboratories, Inc. , a leader in advanced silk fiber technologies, has introduced a groundbreaking development—engineered silk inspired by the caddisfly. This breakthrough represents a significant advancement in fiber technology, offering new possibilities for high-performance materials across various industries.
Caddisflies, often referred to as “Periwinkles” in the Pacific Northwest, are known for their ability to spin silk underwater, which they use to create protective casings in aquatic environments. By leveraging the distinctive mechanical and chemical attributes of caddisfly silk proteins, Kraig Labs has developed a novel silk material designed for enhanced durability in wet conditions. This innovation has the potential to support applications in medical adhesives, biomedical textiles, performance apparel, and next-generation fiber technologies.
Kim Thompson, CEO and Founder of Kraig Labs, emphasized the significance of this development. “Expanding beyond spider silk proteins allows us to explore a wider range of possibilities in silk engineering,” he stated. “By drawing from nature’s diversity, we are creating innovative fibers that align with the evolving needs of modern industries.”
The introduction of caddisfly-based transgenic fiber represents a key milestone in Kraig Labs’ mission to develop superior materials by combining the unique properties of various silk proteins. Utilizing its proprietary silkworm-based production system, the company aims to bring these high-performance fibers to market efficiently and sustainably.
“Incorporating the remarkable adhesive properties of caddisfly silk protein has been a foundational goal in our research and development strategy,” Thompson added. “This achievement is not only a significant step forward for our business but also a testament to the dedication and expertise of our team.”
Jon Rice, COO of Kraig Labs, acknowledged the contributions of the company’s scientific team. “Our success in developing this caddisfly-inspired material reflects the power of combining innovative research with a clear vision,” he noted. “We are excited about the potential applications of this fiber and the opportunities it presents across multiple industries.”
Kraig Labs has filed a provisional utility patent for this pioneering technology as part of its commitment to leading advancements in silk protein engineering.
