A designable twist-densification route to bioactive collagen hydrogel yarns approaching tendon-like mechanics

Reconstituted collagen hydrogels offer the bioactivity that load-bearing tissue engineering requires, but their Pascal to low-kPa moduli have confined them to non-structural roles, and the synthetic and hybrid strategies that close the mechanical gap typically forfeit that bioactivity. We show that a twist-induced dens...
