Silkworms and spiders are capable of generating fibers that are both highly durable and elastic in a short span of time, using a silk solution stored within their bodies at room temperature and normal atmospheric pressure. The dragline silk fiber, wh

Objectives: Vascular replacement is one treatment for cardiovascular disease. However, in blood vessels with a diameter less than 6 mm, the existing artificial vascular grafts may be occluded by thrombus formation or intimal hyperplasia. Thus, new ar

Spider dragline silk has unique characteristics of strength and extensibility, including supercontraction. When we use it as a biomaterial or material for textiles, it is important to suppress the effect of water on the fiber by as much as possible i
