Fig. 5.

Tentative structure of fibrils formed by silk-inspired triblock copolymers (not to scale). By stacking, the silk-like S^E₄₈ or S^H₄₈ blocks, depicted as aligned cylinders, form a μm-long core (blue). The extremely hydrophilic C₂ blocks are shown as green wires emerging from the silk-like blocks and form a hydrophilic corona surrounding the core. (A) C^P₂-S^E₄₈-C^P₂ self-assembled at low pH. (B) Functionalized variants of C^P₂-S^H₄₈-C^P₂ self-assembled at neutral pH. Adapted from Włodarczyk-Biegun et al. (2016a) under Creative Commons License BY-NC-ND 4.0.
