Abstract


The present investigation has been carried out to evaluate the antibacterial activities of Silver nanopartilces synthesized from Azadirachta indica, Tridax procumbens and Aegle marmelos leaves against wound infection causing bacterial pathogens. Antibacterial activity was assessed by well diffusion method. The activities of the AgNps were measured by zone of inhibition and compared with a standard antibiotic Tetracycline. Among the various concentrations (10mg/ml) was found to be very effective. The synthesized AgNps were analysed by colour change, UV Vis spec and SEM. The Green synthesis of silver nanoparticles by the help of plants is a very cost effective, safe, nontoxic, eco-friendly route of synthesis which can be manufactured at a large scale.
