Silver nanoparticles have been prepared by the reduction of silver ions using respectively castor oil (ricinus communis), khat (catha edulis) and sun flower (helianthus annuus) leaf extracts as reducing and stabilizing agents. The as-synthesized material was characterized by using spectroscopic, XRD and TEM techniques. As-synthesized silver nanoparticles are found to have face centered cubic structure with average crystallite size 28 nm. and showed antimicrobial activity against Escherichia coli and Staphylococcus aureus.

Abstract


Silver nanoparticles have been prepared by the reduction of silver ions using respectively castor oil (ricinus communis), khat (catha edulis) and sun flower (helianthus annuus) leaf extracts as reducing and stabilizing agents. The as-synthesized material was characterized by using spectroscopic, XRD and TEM techniques. As-synthesized silver nanoparticles are found to have face centered cubic structure with average crystallite size 28 nm. and showed antimicrobial activity against Escherichia coli and Staphylococcus aureus.
