ABSTRACT
Hydrogels have drawn intensive attention as fascinating materials for biomedicine. However, fabricating hydrogels with injectable and self-healing properties remains a challenge. Herein, we reported a biocompatible poly(N-vinylpyrrolidone)/carboxymethyl cellulose (PVP/CMC) hydrogel with excellent injectable and self-healing properties. The PVP/CMC hydrogel exhibits good biocompatible, injectable, and self-healing properties. The sol-gel transition of PVP/CMC hydrogels demonstrates an outstanding self-healing behavior, and the bisected hydrogels can self-heal within 30 s. The hydrogels have a good swelling ratio, and the swelling ratio increases with increasing amount of CMC in PVP and reaches a maximum of 2850% at a 1.01.5 PVP and CMC ratio. In addition, the hydrogel possesses excellent drug release capacity, and its drug release rate reaches 70%. Moreover, the release of 4-aminosalicylic acid (4-ASA) in the hydrogel can be controlled by adjusting the proportion of the hydrogel. The PVP/CMC hydrogel with excellent biocompatible, injectable, and self-healing properties has great potential for applications in drug release.
