Metastable Liquid–Liquid Phase Separation and Aging Lead to Strong Processing Path Dependence in Mini‐Spidroin Solutions (Adv. Funct. Mater. 15/2025)
Recombinant Silk Proteins Spiders produce silk fibers with exceptional qualities through non-equilibrium pathways. Engineering approaches to mimic fiber pulling include storage and processing of in vitro protein solutions. In article number 2410421, Markus B. Linder and co-workers propose a minimalist phase diagram for an engineered mini-spidroin solution, serving as a guide to various assembly pathways. They observe metastable liquid–liquid phase separation and aging leading to dynamically arrested aggregate or gel states.
