Materials scientists show way to make durable artificial tendons from improved hydrogels

The width of the test material is about 2 mm. view more  Credit: Mutian Hua, Shuwang Wu, and Ximin He/UCLA UCLA materials scientists and their colleagues have developed a new method to make synthetic biomaterials that mimic the internal structure, stretchiness, strength and durability of tendons and other biological tissues. The researchers developed a two-pronged process to enhance the strength of existing hydrogels that could be used to create artificial tendons, ligaments, cartilage that are 10 times tougher than the natural tissues. Although the hydrogels contain mostly water with little solid content (about 10% polymer), they are more durable than Kevlar and rubber, which are both 100% polymer. This kind of breakthrough has never been achieved in water-laden polymers until this study, which was recently published in

(Denis Charlet/AFP via Getty Images) To date, a myriad of possible uses for spider silk have been proposed including medical applications, cosmetics, composite materials for aircraft, protective body armor and incorporation into textiles. If you scour the maker space, you can easily identify up to 10 companies already using spider silk for these various applications. These companies have developed industrial-scale processes to ferment synthetic spider silk in bacteria. The result is a growing industry of sustainably sourced and environmentally friendly material that can supplant other raw materials limited by finite availability. The other aspect of spider silk is that it holds the promise of delivering impressive new functionalities and features for differe
