http://onlinelibrary.wiley.com/doi/10.1002/adfm.201704757/full Hydrogels are the focus of extensive research due to their potential use in fields including biomedical, pharmaceutical, biosensors, and cosmetics. However, the general weak mechanical properties of hydrogels limit their utility. Here, pristine silk fibroin (SF) hydrogels with excellent mechanical properties are generated via a binary-solvent-induced conformation transition (BSICT) strategy.
