Elastin-like polypeptides (ELPs) are promising for biomedical applications due to their unique thermoresponsive and elastic properties. ELP-based hydrogels have been produced through chemical and enzymatic crosslinking or photocrosslinking of modified ELPs. Herein, a photocrosslinked ELP gel using only canonical amino acids is presented.

We found that increasing concentrations of fluorine gradually elongated the gelation time from 194 s for controls to 304 s for 1/5 V-sense/HA hydrogels, while their elastic properties slightly decreased, from 183 Pa for the control to 95.3 Pa for 1/5 V-sense/HA hydrogel at day 0, and from 870 Pa for the control to 588 Pa for 1/5 V-sense/HA

spinal unit, while also permitting complex combinations of movement. Compressive loads are transferred from adjacent vertebral bodies to the IVD tissues. The CEPs act as mechanical mediators and uniformly distribute load across the entire disc [38]. Both the NP and AF work symbiotically to redirect compressive loads toward the vertebral bodies.
The 3D suprastructure simultaneously exhibits the Young's modulus above 300 kPa while retaining a light density of 7.7 mg/cm 3 and the elasticity against up to 80% of the compressive strain. The fabricated 3D CCS opens a new pathway for designing lightweight, strong, and superelastic materials.
