In this study, silver nanoparticles (AgNPs) were made quickly and safely without the use of harmful chemicals by combining silver nitrate in aqueous solution with Mulberry leaf extract. The extract from mulberry leaves works as a stabilising and reducing agent. A peak maximum is visible in the UV-Vis spectroscopy at 430 nm. The roughly sphericalshaped synthetic AgNPs seen in the transmission electron microscopy (TEM) image have a size range of 15 to 20 nm. The average particle size is assessed to be 10 nm in the TEM picture of the Nano Silver solution sample produced by the microwave aided approach. A distinct absorption band about 415 nm is visible in the UV-vis spectra of silver nanoparticles made with microwave assistance (AgNPs mw). Silver nanoparticle peak variations in the UV-Vis spectrum of AgNPsmw after two months of storage are minimal. [ABSTRACT FROM AUTHOR]

Present is a low-cost and environmentally beneficial approach for producing silver nanoparticles from discarded pineapple leaves utilising microwave-assisted extraction. AgNPs are produced environmentally friendly using a straightforward reduction technique and silver nitrate. The ideal conditions for green synthesis are determined by taking into account a number of factors, such as the silver nitrate concentration (5–25 mM), the incubation period (2–24 h), and the sample volume (2–8 mL). The reduction of silver metal ions into silver nanoparticles is indicated by the appearance of an absorption band in the UV-Vis spectro-photometer between 400 and 500 nm. Longer run times, higher silver nitrate solution concentrations, and larger sample volumes are all observed to improve absorption intensity. The green synthesised silver nanoparticles range in size from 40 to 150 nm and exhibit hexagonal spherical shapes, according to FE-SEM studies. Furthermore, the presence of green synthesised AgNPs is confirmed by FTIR and XRD studies. In comparison to non-microwave-assisted treatment, silver nanoparticles treated with a microwave show increased antibacterial activity against Escherichia coli, Bacillus subtilis, and Staphylococcus aureus. Silver nanoparticles must be present at a minimum of 60 g/mL to suppress bacterial growth. Overall, this study provides an avenue with substantial potential for the environmentally friendly and economically advantageous green synthesis of silver nanoparticles employing the microwave-assisted technique [ABSTRACT FROM AUTHOR]
