Recently, plant mediated synthesis of silver nanoparticles is gaining huge and remarkable importance as compared to available and most widely used physical and chemical methods. In the present study, silver nanoparticles were synthesized using Arjuna (Terminalia arjuna Wight & Arn.), Baheda (Terminalia belerica Roxb.) and Cotton (Gossypium herbaceum L.) plant extracts. Phytochemicals present in plant extracts carry out bio-reduction of silver ions and results in change in the color of the solution. The Ag NPs formed were confirmed by UV-VIS spectroscopy and TEM, SEM and PSA analysis were used to determine the shape and size of the synthesized nanoparticles. Further, antibacterial and antifungal activities of biosynthesized Ag NPs were assessed by well diffusion method by measuring the zone of inhibition. Ag NPs synthesized using all three plant extracts showed significant antibacterial and antifungal activity against bacterial (Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa) and fungal (Aspergillus niger, Candida albicans and Trichoderma sp.,) strains. It was observed that, bacterial and fungal growth was inhibited with increase in volume of Ag NPs. Maximum inhibitory activity was exhibited to Ag NPs synthesized from cotton plant extract. This study highlights, preparation of plant extracts and their use in synthesis of silver NPs and its novel potential use as an antimicrobial agent.
