ABSTRACT

An eco-friendly approach for the preparation of silver nanoparticles (AgNPs) from silver nitrate solution using ethanolic Ficus racemosa fruit extract was investigated. The reduction of silver ions in solution was monitored using UV–visible absorption spectroscopy, and the surface plasmon resonance of AgNPs at 435 nm was observed. The proper condition to biosynthesize AgNPs using Ficus racemosa fruit extract was optimized by UV–visible absorption spectroscopy. The biosynthesised nanoparticles were characterised using scaning electron microscopy (SEM), The prepared AgNPs were spherical in shape, and their average particle size determined by SEM was about 75.6 to 145 nm. Furthermore, the AgNPs were found to exhibit effective antibacterial activities against Escherichia coli and Staphylococcus aureus.
