Injectable hydrogels have become increasingly important in the fields of tissue engineering and drug delivery. However, their biol. applications are greatly limited by the weak mechanics and poor stability under a physiol. environment. Herein, we developed a stable, strong, and injectable hydrogel by linking strong micelle crosslinking with tetra-armed PEG. This dual crosslinking strategy has not only made hydrogels nonswelling but also maintained the relative integrity of the gel network during the degradation process, both of which work together to ensure the mech. strength and stability of our hydrogel under a physiol. environment. A compressive stress of 40 MPa was achieved at 95% strain, and the mech. properties could remain stable even after immersion into a physiol. environment for two months. Besides, it also showed outstanding antifatigue properties, good tissue adhesion, and good cytocompatibility. On the basis of these characteristics, these dual crosslinking injectable hydrogels would find appealing application in biomedicine especially for the repair of load-bearing soft tissues.
