A Physically‐Based Machine Learning Approach Inspires an Analytical Model for Spider Silk Supercontraction

open access: yesAdvanced Functional Materials, EarlyView.
Starting from an experimental database, a physically‐based machine learning approach is used to gain new insights into spider silk supercontraction. These insights inspire a microstructure‐based analytical model that quantitatively predicts supercontraction based on protein primary structure properties. New experiments to further elucidate the physical

An Engineered Recombinant Spider Silk Protein Providing Disulfide‐Locked Control over Self‐Assembly and Fiber Formation

open access: yesAdvanced Functional Materials, EarlyView.
Using atomic structure and local stability information, recombinant aciniform spider silk proteins are rationally engineered to incorporate a chemically switchable disulfide bond to prevent fiber formation. When disulfide‐locked, these proteins cannot form continuous fibers, whereas the unlocked (reduced) state can.
