Abstract

In the present paper, silver nanoparticles (AgNPs) were synthesized using the Brassica oleraceae fruit extract under the simple and eco-friendly conditions. The reaction between silver nitrate, as metal source, and aqueous extract of Brassica oleraceae fruit, as reductant agent, produced AgNPs in high yield. The formation of AgNPs was confirmed by means of UV-Vis spectroscopy and scanning electron microscopy (SEM) was used for characterization of morphology and size of silver nanoparticle products. The investigation of diverse reaction parameters revealed that reductant concentrations, reaction pH, mixing ratio of the reactants and interaction time affected the size and morphology of synthesized AgNPs. AgNPs with 32.74 nm size and amorphous, based on SEM images, were produced within 24 h interaction period. AgNPs also showed a good antibacterial activity against Escherichia coli.
