Nanotechnology is one of the most important scientific areas that exhibit rapid advancements and applications that can establish extraordinary properties like biosensing, electrical, magnetic, thermal, metal detection, optical sensing, and catalytic traits when particle size is reduced. The methods used to create nanoparticles require various inputs, including highly advanced machinery and enormous quantities of energy, which forbid extreme circumstances like high temperatures, voltages, etc. Green nanoparticle synthesis is becoming more and more popular due to its ease of use, affordability, and environmental friendliness compared to traditional physical and chemical synthesis techniques. Ficus auriculata (FA), a deciduous plant in the Moraceae family, was used in this study to create silver nanoparticles using a green pathway. Techniques, including ultraviolet-visible spectroscopy, XRD, and SEM, were used to characterize the nanoparticles synthesized (FA-AgNPs). The color changed from pale yellow to dark brown as observed visually, and the creation of silver nanoparticles in the solution was indicated by the absorption peak in the UV-visible spectra at 450 nm. The generated silver nanoparticles' crystalline shape was confirmed by XRD studies. By using EDX analysis, the AgNPs' elemental composition and surface morphology were determined. The disc diffusion technique was used to conduct the antibacterial analysis of the FA-AgNPs against Escherichia coli (ATCC 25922) and Staphylococcus aureus (ATCC 25923). FA-AgNPs exhibited excellent antibacterial properties against the selected microbial strains. The study's outcome reveals that synthesized FA-AgNPs can be explored to develop various products for biomedical applications. Furthermore, potato starch-chitosan-based nanocomposites were prepared using FA-AgNPs, and their antibacterial property was analyzed. [ABSTRACT FROM AUTHOR]
