The Technology
Aerogels are like hydrogels in which the liquids have been replaced by a gas. Recently, natural protein-based aerogels found to be very interesting in the biomedical and biomaterial fields due to their biocompatibility and degradability. Current approaches still use harsh denaturation conditions and underestimate the importance of proteins inherent characteristics such as biological functionality and folded structure. Furthermore, these strategies conceal the potential to utilize and translate them into future smart-biomaterial applications such as wound dressing and biomolecules immobilization. Researchers developed, synthesized, and characterized protein-based aerogels while preserving their 3D native folded structure and activity.
