Hydrogels are polymer materials made mostly from water. They can be used in a wide range of medical and other applications. However, previous incarnations of the materials suffered from repeated mechanical stress and would easily become deformed. A novel crystal that can reversibly form and deform, allows hydrogels to rapidly recover from mechanical stress. This opens up the use of such biocompatible materials in the field of artificial joints and ligaments.
Many of us suffer the occasional sports injury or experience some kind of pain relating to joints and ligaments at some point in our lives. For serious injuries of this nature, there is often little that can be done to repair the damage. But a new development in the field of water-rich polymer materials known as hydrogels could find its way to the operating room in around 10 years or so. And they should stand up to the same mechanical stresses our natural joint and ligament tissues experience too. They’re called self-reinforced gels.
