“…Zeta potential is one of the important parameters for analyzing the properties of the nanoparticle surface and also determining the stability of the dispersion. Previous studies have corroborated that zeta potential measurement showing values more than +25 mV or <−25 mV may have a good degree of stability [40]; further, the negative charge on the AgNPs ions may also be influenced by the presence of biomolecules obtained from the plant extracts [41]. In our study, the zeta potential value of the dispersed AgNPs was found to be −10 mV which is similar to the earlier reported studies [35,39].…”

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.

“…[6,9,10] According to the literature, there are plenty of protocols focused on the production of hybrid/composite materials based on Ag NPs, whose architecture is driven by different synthetic methods and reaction mechanisms. [11][12][13][14][15][16][17] While the precise reasons for this unique chemistry and physics are unknown, the observed structures, their reproducibility, and synthetic control this reaction offers, there is plenty of room to find innovative possibilities for new technologies. [18,19] Ag NPs have been proven to be most useful because they have excellent antimicrobial properties against lethal viruses, microbes/germs, and other microorganisms.…”

Pathogens (bacteria, fungus and virus) are becoming a potential threat to the health of human beings and environment worldwide. They widely exist in the environment, with characteristics of variety, spreading quickly and easily causing adverse reactions. In this work, an Ag-based material is used to be incorporated and functionalized in polycotton fabrics using pad-dry-cure method. This composite proved to be effective for inhibiting the SARS-CoV-2 virus, decreasing the number of replicates in 99.99% after an incubation period of 2 minutes. In addition, it caused 99.99% inhibition of the pathogens S. aureus, E. coli and C. albicans, preventing cross-infections and does not cause allergies or photoirritation processes, demonstrating the safety of its use.

Nanoparticles (NPs) synthesized by green techniques have received reseachers attention due to their unique physicochemical characteristics and their immense applications in various field. In recent years, synthesis of metal nanoparticles (MNPs) by green technique using plant extracts has become centre of attraction researchers because these NPs have low hazardous effect on the environment and also low toxicity for the human body. The plant extract contains various secondary metabolites which act as a reducing and stabilizing for various metallic nanoparticles synthesis. The non-biological methods i.e. the conventional chemical and physical methods are highly toxic and have serious hazardous effect on human beings and other organisms. On the other hand, the biological or green synthesis of metallic nanoparticles is less expensive, single step process, eco-friendly and also shows effective result. Different plant extracts has been used successfully with various metallic nanoparticles such as, copper, silver, gold, palladium, platinum and zinc oxide. Also, these nanoparticles have potential to cure many diseases such as cancer, hepatitis, malaria, and other deadly diseases. This paper presents a review on plant mediated synthesis of metallic nanoparticles by green technology.
