讲座摘要:

Natural proteins display critical structural and bioactive properties that have evolved in nature for millions of years. However, depending on the specific protein, there may be useful functions, such as mechanical toughness, while other critical features may be more limiting, such as cell compatibility or a broader range of mechanical properties. Silk proteins, as a building blocks for biomaterials construction, combine a unique properties of high mechanical performance and overall biocompatibility. This has led to their use in artificial vascularized tissues, nerve guides and functional soft/hard scaffold and recently silkworm silk has received Food and Drug Administration approval for expanded biomaterials device utility. Yet this wonder-material is not without its own challenges. These include the extreme shear sensitivity of silk fibroins and their propensity to aggregate upon extraction and thus it requires more biologically sensitive processing routes. Our research addresses these fundamental limitations by exploring a platform technology, based on microfluidics, that unlocks investigation of unstable fibroins, as well as other aggregation-prone proteins, processing and routes towards the use of material in contact with cells enabling us to explore possible applications in biomedicine.
