Objective: The present study was aimed to study at investigating the antibacterial potential of silver nanoparticles (AgNPs) coated cotton fabrics against different pathogens and also for their wound healing property using fibroblasts cells. Materials and Methods: The leaf extracts of Peltophorum pterocarpum were used for the synthesis of AgNPs and were characterizing using ultraviolet-visible spectrophotometer, transmission electron microscopy, energy dispersive X-ray (EDX) spectroscopy, dynamic light scattering analysis, and zeta potential measurement. The AgNPs were coated on cotton fabrics and tested for their antibacterial efficacy using agar well diffusion method. The wound healing property of synthesized AgNPs was tested using fibroblast 3T3 cells. Results: The plant extracts of P. pterocarpum were utilized for AgNPs. The optimum condition for synthesizing AgNPs was found to be 1 mg/ml plant concentration, 7 pH, 1 mM silver nitrate concatenation, and incubation temperature of 37°C. The shape of synthesized AgNPs was found to be spherical with an average size between 20 and 50 nm, and elemental silver peaks were confirmed by EDX spectrum. The cotton fabrics coated with AgNPs show good zone of inhibition against all the tested pathogens and the treated fabrics were also characterized using scanning electron microscope which reveals the presence of AgNPs on the fabrics. The scratch assay reveals that the AgNPs have good wound healing activity when tested against fibroblast 3T3. Conclusion: The present results conclude that the synthesized AgNPs have good stability with potent antimicrobial activity when coated with cotton fabrics. The AgNPs also found to have good activity significant wound healing activity when tested using fibroblast cells.

Abstract The development of cellulose-based textiles that are functionalised with silver nanoparticles (AgNP), synthesised according to a green approach, and offer protection against ultraviolet (UV) radiation and pathogenic bacteria is very important today. In the present work we demonstrate the environmentally friendly approach to obtain such textile material by AgNP synthesis directly (in-situ) on cotton fabrics, using water extracts of plant food waste (green tea leaves, avocado seed and pomegranate peel) and alien invasive plants (Japanese knotweed rhizome, goldenrod flowers and staghorn sumac fruit) as reducing agents. The extracts were analysed for their total content of phenols and flavonoids and their antioxidant activity. The synthesised AgNP on cotton were round, of different size and amount depending on the reducing agent used. The highest amount of AgNP was found for samples where Japanese knotweed rhizome extract was used as reducing agent and the lowest where extracts of goldenrod flowers and green tea leaves were used. Regardless of the reducing agent used to form AgNP, all cotton samples showed excellent protection against E. coli and S. aureus bacteria and against UV radiation with UV protection factor values above 50. The best results for UV protection even after the twelve repetitive washing cycles were found for the sample functionalized with AgNP synthesised with an extract of the Japanese knotweed rhizome. Due to the presence of AgNP on cotton, the air permeability and thermal conductivity decreased. AgNP had no effect on the change in breaking strength or elongation of fabrics. Graphic abstract
