Biodegradable High-Strength Hydrogels with Injectable Performance Based on Poly(l-Glutamic Acid) and Gellan Gum

Currently, biodegradable hydrogels are one of the most promising materials in tissue engineering. From the perspective of clinical needs, hydrogels with high strength and minimally invasive implantation are preferred for the reconstruction of load-bearing tissues. In this work, a biodegradable, high-strength, and injectable hydrogel was developed by one-step photo-cross-linking of two biomacromolecules, polyethylene glycol acrylated...
