Abstract
- 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]
