Plasma-treated bamboo wound dressing functionalized with green-synthesized silver nanoparticles

The present study investigates the fabrication of a wound dressing using oxygen plasma-treated regenerated bamboo spunlace nonwoven fabric coated with green-synthesized silver nanoparticles (AgNPs) derived from Tridax procumbens leaf extract. The fabricated wound dressing exhibits enhanced physical properties, including increased mass per unit area, elongation, air permeability, water vapour permeability, and wickability. A slight reduction in thickness and breaking force is observed. The wound dressing exhibits significant antimicrobial activity against wound pathogens, supported by field emission scanning electron microscopy (FESEM) analysis, which reveals a higher distribution of AgNPs on the plasma-treated surface. Additionally, the fabricated wound dressing shows improved free swell absorptive capacity, making it suitable for the treatment of moderate to heavily exuding wounds. These findings highlight the potential of this novel wound dressing for advanced wound care applications.
