Rapid and Eco‐Friendly Preparation of Antibacterial Gauze by Alkali‐Acid Redeposition of Quercetin on Gauze Fiber and Subsequent Ultraviolet‐Assisted Reduction of Silver In Situ

Rapid and eco-friendly preparation of biomedical materials is significant for practical applications. This study proposes a simple two-step method preparing silver nanoparticles (AgNPs)-functionalized gauze dressings (Ag-Q-G) with antibacterial activity in green time-efficient manner that requires <10 min. A smooth uniform quercetin coating formed on the fibers using alkali–acid redeposition 10 s. Subsequently, AgNPs are rapidly (in 5 min) firmly deposited quercetin-coated by ultraviolet irradiation an AgNO3 solution. The vitro results indicate Ag–Q–G exhibits excellent activity, rate 99.57% ± 0.52% against Staphylococcus aureus 95.59% 1.50% Escherichia coli, while maintaining acceptable cytocompatibility. An animal reveals Ag-Q-G reduces infection promotes wound healing rat dorsal total cortical model. approach provides option commercial production dressings.
