Tougher hydrogels to rival rubber

Tougher hydrogels to rival rubber - Exceptionally tough and stretchy new hydrogels have been developed by US and South Korean scientists.1 The gels, which may eventually find applications in contact lenses and tissue engineering, are 10 times tougher than cartilage and can stretch to 20 times their original length without suffering permanent damage.(10.1038/nature11409)
