Abstract
Remarkable properties of hydrogels are compromised by failure to recover from damage, bringing their intended functions to an end. To address this, hydrogels can be functionalized with self-healing property to enable them to restore themselves after damage, thus, extending their lifetime. Herein, hydrogels were prepared by cross-linking acrylamide-modified β-chitin (Am-β-Chn) with alginate dialdehyde (ADA) to form Schiff base, showing IR characteristic peak at 1650 cm-1, attributed to the stretching vibration of CN. The dynamic Schiff base and H-bond rendered the double crosslinked hydrogels self-healing as demonstrated by continuous step strain rheology. Characterization of the hydrogels revealed excellent biocompatibility, biodegradability, injectability and self-healing properties. Furthermore, the wound healing property of the hydrogels was investigated in vivo using zebrafish as a model system. Indirect application of Am-β-Chn/ADA hydrogel remarkably led to ~87% wound healing as compared to control which gave ~50%, suggesting that hydrogels are effective in accelerating wound healing. However, a clear understanding of the exact mechanism of its wound healing property remains to be investigated. To the best of our knowledge, this is the first innovation of developing novel double crosslinked Am-β-Chn/ADA hydrogels with both self-healing and accelerated wound healing properties, directly from marine-food wastes.
