Abstract
Silver nanoparticles were successfully synthesized by a simple green and eco-friendly route, using Olax acuminata leaf extract for the first time. Preliminary confirmation for the formation of silver nanoparticles was done visually by colour change from light yellow to dark brown and by UV-visible spectrophotometer. Further the synthesized nanoparticles were characterized by FTIR, XRD, TEM and SEM. The catalytic activity of the synthesized silver nanoparticles was investigated by the degradation of methylene blue and photocatalytic activity by the degradation of methyl orange. The synthesized silver nanoparticles are found to have a good catalytic effect on the reduction of both the dyes which is confirmed by the decrease in absorbance maximum values with time using UV-visible spectrophotometer. Further the antibacterial activity was evaluated against four bacterial species i.e., Staphylococcus aureus, Bacillus subtilis, Pseudomonas aeruginosa and Escherichia coli at four different concentrations (5, 10, 15 and 20 μg/mL) and was assessed by the zone of inhibition (mm). The highest activity was found against Staphylococcus aureus (11 mm) and it was found that bacterial growth significantly reduced in a dose dependent manner. Antibiotic ciprofloxacin was used as the standard in the antibacterial assay.
