Fibrous networks constructed from high aspect ratio protein building blocks are ubiquitous in nature, but the functional advantage of such building blocks over globular proteins is not understood. Here, using shear rheology and small-angle neutron scattering, the authors characterise the mechanical and structural properties of photochemically crosslinked protein L and fibrin networks and show that aspect ratio is a crucial property that defines network architecture and mechanics.
