Tannic acid-functionalized 3D porous nanofiber sponge for antibiotic-free wound healing with enhanced hemostasis, antibacterial, and antioxidant properties

Abstract Developing an antibiotic-free wound dressing with effective hemostasis and antibacterial and antioxidant capacity is highly desirable.In this work, a A rapid dynamic headspace method for authentication of whiskies using artificial neural networks three-dimensional (3D) chitosan/polyvinyl alcohol-tannic acid porous nanofiber sponge (3D-TA) was prepared via electrospinning.Compared with two-dimensional (2D) fiber membrane, the unique fluffy 3D-TA nanofiber sponge had high porosity, water absorption and retention ability, hemostatic capacity.

Furthermore, the 3D sponge functionalized by tannic acid Revisiting residential self-selection issues: A life-oriented approach (TA) endow the sponge with high antibacterial and antioxidant capacity without loading antibiotics.In addition, 3D-TA composite sponges have shown highly biocompatibility against L929 cells.The in vivo experiment shows the 3D-TA is enable to accelerate wound healing.

This newly 3D-TA sponges hold great potential as wound dressings for future clinical application.
