Synthesis of nanoparticles was done by green method. Silver nitrate was used as the silver precursor, while the fruit juices of the citrus fruits (Citrus sinensis, Citrus limetta, Citrus aurantifolia, Citrus paradisi) were used as reducing and stabilizing agents. The nanoparticle formation was confirmed with the visible colour change from colourless to characteristic reddish brown. the surface plasmon resonance peak was at 451 and 452 nm for the silver nanoparticles The antimicrobial activities of these nanoparticles were studied against Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa and Bacillus subtilis. Generally, MIC values of the samples against the microorganism tested ranged from 25-100mg/ml. Pseudomonas aeruginosa was the most sensitive (while Staphylococcus aureus and Bacillus subtilis were the least sensitive to the silver nanoparticles).
