Biosynthesis of Silver Nanoparticles Enhanced Antibacterial Silk Face Covering

Biosynthesis of silver nanoparticles (AgNPs) using plant extracts as reducing agents has recently attracted interest an environmentally friendly and cost-effective approach. In this study, biosynthesized were coated on cotton fabric antimicrobial outer middle layer in a silk face mask. The AgNPs synthesized characterized by scanning electron microscopy (SEM) energy-dispersive X-ray spectroscopy (EDX). A solution 100 ppm was the exhaustion process quantified according to procedures AATCC 100–1999. Top performance characteristics barrier covering determined ASTM F3502–2021. spherical with particle size ranging 35–88 nm. SEM images AgNP-coated fabrics showed good dispersion that decreased after washing, 99% reduction viable E. coli S. aureus 30 washing cycles. developed also offered sufficient sub-micron filtration efficiency airflow resistance level II under classification.
