چکیده انگلیسی


• Erigeron annuus (L.) pers flower extract as reducing, and capping agent for AgNPs synthesis.
• Fabrication of green-synthesized nano silver on to cotton fabric and leather.
• Antibacterial activity against odor-causing bacterial pathogens.
• Coating with the help of ultrasonic water bath.
• Suitable for fabricate on cotton fabric and leather.

This study aims to investigate the green synthesis of silver nanoparticles (AgNPs) by Erigeron annuus (L.) pers flower extract as reducing and capping agent, and evaluation of their antibacterial activities for the first time. The obtained product was confirmed by UV–Vis spectrum, high resolution-transmission electron microscopy, energy-dispersive X-ray spectroscopy, Fourier transform infrared spectroscopy, and X-ray diffraction studies. The optimum AgNPs production was achieved at pH 7, metal silver (Ag+ ion) concentration of 2.0 mM, flower extract concentration 4%, and time 335 min. In addition, the antibacterial activity of cotton fabrics and tanned leather loaded with AgNPs, commercial AgNPs, flower extract, Ag+ ion and blend of flower extract with AgNPs were evaluated against Gram-positive odor causing bacteria Brevibacterium linens and Staphylococcus epidermidis. The results showed maximum zone of inhibition (ZOI) by the cotton fabrics embedded with blend of flower extract and AgNPs against B. linens. The structure and morphology of cotton fabric and leather samples embedded with AgNPs, Ag+ ion and blend of flower extract with AgNPs were examined under field emission scanning electron microscope.
