23_09b/2013Self-Assembly: Reinforcement of Shear Thinning Protein Hydrogels by Responsive Block Copolymer Self-Assembly (Adv. Funct. Mater. 9/2013)

Triblock copoylmers with associative protein midblocks and thermoresponsive endblocks form shear thinning hydrogels that can be injected at low temperature. On page 1182, Bradley D. Olsen and co-workers report that when warmed to body temperature, the gel is responsively reinforced as the endblocks self-assemble into a secondary block copolymer network, leading to large increases in modulus and yield stress, and decreased erosion and creep compliance.
