Abstract

The present work reports the synthesis of silver nanoparticles (Ag NPs) by chemical as well as biological approaches. Ag NPs have been synthesized using different plant extracts such as Aloe vera, Syzygium aromaticum (clove), Musa (banana leaf), and Citrus X Sinensis (orange peel). The effect of various reducing agents has been examined on the shape and morphology of the synthesized Ag NPs. The synthesized Ag NPs have been characterized using UV–visible spectrophotometer, Dynamic Light Scattering (DLS), and Transmission Electron Microscopy (TEM). The average size of the synthesized Ag NPs has been confirmed by DLS characterization as 64 ± 11 nm, 106 ± 8 nm, 500 ± 14 nm, 281 ± 9 nm and 105 ± 7 nm, respectively. when synthesized using Aloe vera, Syzygium aromaticum, Musa, Citrus X Sinensis, and trisodium citrate (TSC), respectively. The synthesized Ag NPs have been used for screening antibacterial activity against Escherichia coli, Staphylococcus aureus and Bacillus subtilis. The synthesized Ag NPs have also been evaluated for their bactericidal property against wastewater from polluted rivers and other water sources and have been found appropriate for use in bacteriological and wastewater treatment.
