| contents | Multifunctional Carboxymethyl Chitosan/Sodium Alginate/Fucoidan Hydrogel as a Dressing for Hemostasis and Skin Wound Healing. Gai, Xinyue Bi, Yinghao Zhao, Wen Ren, Changlong Chang, Ming Zhang, Miansong Cui, Tingting Liu, Xue Jia, Airong Wound healing is a complicated process that involves hemostasis, antibacterial defense, and tissue regeneration. Conventional treatment methods, such as surgical suturing, have inherent limitations, necessitating the exploration of new ones. Hydrogels can create a moist environment that facilitates wound healing, making them an ideal material for wound healing. In this study, a procoagulant polysaccharide mixture (carboxymethyl chitosan/sodium alginate/fucoidan; CAF) was designed. Hydrogels were prepared using CAF and an oxidized starch/tannic acid blend (OT) at different ratios. Through comprehensive evaluations, such as gelation time, swelling capacity, and antibacterial efficacy, an optimal hydrogel (COT) was identified. This COT hydrogel was formed by mixing 3% CAF and OT solutions at a ratio of 2:1 (/). The associated gelation process occurred rapidly within 13 s. COT hydrogel exhibited self-healing properties, and a high swelling rate (~3109 ± 74%). It also demonstrated high antibacterial activity, facilitating enhanced protection against infection. Additionally, COT hydrogel exhibited biocompatibility and biosafety. COT hydrogel demonstrated low cytotoxicity on mice fibroblast cells (L929) and good hemocompatibility in vitro. Moreover, in vivo evaluations revealed that it did not cause skin irritation or allergic reactions. Importantly, COT hydrogel significantly outperformed the commercially available hydrogel with its hemostatic and wound healing performance ( < 0.001, < 0.01). |
